Journeys in the Back of Beyond: Adventures on the Colorado Plateau

 

Devils Garden in Arches National Park
What is an adventure anymore? 

I ask my students to describe the meaning in one of my offbeat assignments in my geology courses and I get all kinds of answers. Many will describe a experience from our local educational camp in the Sierra Foothills, or an excursion they took to a local river or lake. Many of them have almost never left the city limits, and camping in the Sierra to them is terra incognita, far beyond their experience or expectation. 

I've always known I've had a blessed life in many ways, and what has made it especially rich is the privilege of leading my students on true adventures way out there in America's Back of Beyond, the Colorado Plateau and the Basin and Range country. I've just returned home from one of those journeys.

In Zion National Park

"Back of Beyond" is informally defined by Merriam-Webster as "a place that is very far from other places and people: a remote place". There are literary connections in the writings of Edward Abbey and C.J. Box, and a 1954 documentary from Australia. It is also the name of one of the finest bookstores in Utah. Outside of Alaska, some of the wildest and remote country in the United States is indeed the Colorado Plateau and the Great Basin, and to me it is some of the finest scenery in the world, and its geological story is fascinating. And...the land is endangered.

I'd like you to experience this country, if only through narrative and photography. I hope you will join me over these next few weeks as I describe our experience in a series of blog posts, and perhaps understand why we need to take action to protect the heritage of these fragile lands.

As usual, my ambitions often exceed my time allocation, so forgive me if delays occur in new postings!

About That Bucket List...What Would You Do To See These Places?

Horseshoe Bend on the Colorado River
So...about that bucket list of yours. 

Surely you have one. If you don't, what's keeping you from making one? Here's a version I promoted a few years back (I've made it to around 70% of them so far and feel exceedingly lucky to have been able to do so).

In any case, how many of the following are (or should be) on your personal list? Possibly Grand Canyon, Zion, Bryce Canyon, Arches, Petrified Forest, Capitol Reef, Yosemite, Great Basin, or Canyonlands National Parks? What about Ancestral Pueblo cliff dwellings at places like Bear's Ears or Grand Staircase-Escalante? Finding ancient petroglyphs along the Colorado River? Or searching for dinosaur bones? How would your life be changed if you could somehow do all these things...in one trip? It's possible!
Grand Canyon National Park
There is no place on this planet like the Colorado Plateau. It's hard to find anyplace else on Earth where the crust remained relatively stable for upwards of a billion years, accumulating several miles of horizontal sediments, only to be lifted up rapidly in the last few million. The Colorado River and her tributaries then stripped away much of the sedimentary cover, and cut deep into the underlying metamorphic rocks. Those metamorphic rocks record a violent geologic history of colliding landmasses and mountain-building. The resulting landscape is one of the most beautiful regions imaginable.
Angels Landing Trail in Zion National Park, Utah
The plateau country is a training ground for geologists and earth scientists, and has been since the days of John Wesley Powell and Joseph Ives, who were the first to lead research parties into the region (they didn't "discover" the plateau, of course; Native Americans have known the region for thousands of years). If you are curious about learning geology in this incredible region, you might consider joining us as a student (of any age) on our geology field studies course Geology 191: Geology of the Colorado Plateau, offered under the auspices of Modesto Junior College in Modesto, California. The course is designed to fulfil the curiosity and build the skills of lay geologists and archaeologists as well.
Mesa Arch in Canyonlands National Park
Our field course will be a grand loop through the plateau country, with investigations of the Mojave National Scenic Preserve, Grand Canyon, Zion, Bryce Canyon, Arches, Canyonlands, Petrified Forest, Capitol Reef, Great Basin and Yosemite National Parks, as well as many monuments, including Bear's Ears, Grand Staircase-Escalante, Natural Bridges, Navajo, and Hovenweep. It will be an unforgettable two week trip from June 3-17, 2025, beginning and ending in Modesto, California. Further information will be found soon here and at my school website. 
Petroglyphs on the plateau
It's not a comfortable trip...we travel in school vans (which of course are known for their luxuriousness!), we camp every night, and the days can be hot, windy, cold, or stormy, and we are out in the middle of anything that happens. But we are staying in beautiful places each night, and there are even showers and laundry available every third day or so! Extensive hiking is not required, but there will be many chances to explore the trails in each park and monument.
Petrified Forest National Park
Geology 191 is a 3-semester-unit course. By end of the course, you will be able to see the landscape the way geologists do: by identifying rocks, minerals and fossils, and interpreting the geological history of an area by working out the sequence of events as exposed in outcrops. If you are a science teacher, you will come home with a collection of photographs that illustrate most of the important principles of geology, and a selection of rocks, minerals and fossils that will make a great classroom teaching tool (legally collected, of course; there are many localities outside of protected parks from which to collect samples). You will also gain some mastery of the archaeology and culture of the plateau region, the home of the Ancestral Puebloans, the Fremont people, the Navajo, the Utes, and others.
Canyonlands National Park, Utah

The cost of the trip (still to be officially determined) will be $850 plus the cost of tuition (Currently $46 per unit for California residents, and around $225 per unit for out-of-state residents). The cost includes transportation, food, camp fees, and entrance fees. Participants would want to bring a few dollars along for showers, laundry, and souvenirs.  The food is tasty and plentiful (everyone helps cook and clean!), and the school vans...are vans.
House-on-Fire Ruin, Bear's Ears National Monument
For those of you who live in the Modesto region, we are having an organizational meeting in April which will also be available as a Zoom session. Details will be provided later on.

If you are not in the area, we will be glad to arrange for transportation from nearby airports and train stations (we actually have an Amtrak station in town). Enrollment can be completed online once you are registered with the college (http://www.mjc.edu). Please contact me with any questions you may have.
Bryce Canyon National Park
Hope to see you out there, back of beyond!

Heading Out to the Back of Beyond on the Colorado Plateau!

Geotripper may go quiet for a week or two, as I will be on the road with twenty of my best students out on the Colorado Plateau, the incredible region surrounding the Four Corners. I've been dreaming of this trip for a year now, as I had to start making group camping reservations last July! It's getting crowded in some of the places like Grand Canyon and Zion, but I've learned over the years that there are some pretty quiet places out there as well. When I started blogging a decade ago, one of my first ideas was a blog series about the places we visit on our field studies journey. I am reposting the introduction both for my students, but for anyone out there who might be traveling in the region and might want to know a little more about the lands they are passing through.



From July 1, 2008:

Please forgive me for filling the feeds with such a long post, but I wanted to pull together an annotated list of the blog posts of my just completed journey through the geological history of the Colorado Plateau. It turned into a massive project that lasted more than a year, and included seventy different postings and more than a hundred photos. Don't feel compelled to try reading it, but I hope you enjoy it if you do. If it lacks precise continuity and style, remember that I had no idea how it would end when I started it and I had no editor! I've been taking students on the plateau for twenty years, and it has proven to be one of the best places on the planet to learn earth history.

Time Beyond Imagining, the first post back in June of 2008 introducing the concept that would guide the entire series. I had no idea what I was getting into!

Time Almost Beyond Imagining: Who Do the Magic that Hoodoo? My favorite title for a discussion of a unique park near the Jemez Caldera, Kasha-Katuwe Tent Rocks National Monument

Time Almost Not Beyond Imagining: Recent Volcanism on the Colorado Plateau and Deep Time Although I had reached the last million years of a two billion year history, I felt a need to try and describe the immensity of geologic time, using the ruins of Bandelier National Park and the Jemez Caldera

Time Beyond Imagining - Where did the Ancient Enemy Go? The "disappearance" of the Ancestral Pueblo people is explored at Bandelier National Monument

Time Beyond Imagining: Why Can't We Touch the Venus de Milo? Once again, I thought I was done, but found a series of fascinating (to me) stories about research in the limestone caverns on the plateau. I began with a rant about preserving these wonderful caves that took us to Rome and Paris, of all places

Holy Crap, Batman! The Bat Cave is Full of it! Bat Cave in western Grand Canyon, and bat-sh*t. Lots of it, sort of

Holy Smokes, Batman, that crap is on fire! I was saving my best titles to the last, I guess. A horrific crime against science at Rampart Cave in the Grand Canyon


Time Beyond Imagining - A Final Struggle for Life on the Colorado Plateau I imagine the death of the very last mammoth on the Colorado Plateau

Time Beyond Imagining: The End of the Story, or the Beginning? In the final post of the series, I discuss the arrival of humans on the plateau, and how humans change the land they occupy. I also tip my hat to Ken Burns and his series on "The National Parks: America's Greatest Idea". The parks are the laboratories in which I and my students study the history of the earth.

So there you go: 71 posts that tell a story encompassing 2 billion years as it is exposed on a very special part of the earth's surface: the Colorado Plateau, covering parts of Arizona, Utah, Colorado, and New Mexico. Congratulations if you ever made it through the whole thing. I never realized I was writing the equivalent of an entire book, but it was a story I truly enjoyed telling, and I also deeply appreciated the feedback that many of you provided.

An Incredible Spot in the Mojave Desert, the Hole in the Wall. You could see it for yourself this summer

Summer is coming soon. If you are casting about wondering what to do, how about the adventure of a lifetime? Our department is offering a dyad class, Geology 191/Anthropology 191, the Geology and Anthropology of the Colorado Plateau, and it is an incredible chance to check out some marvelous geology along our southwestern tier of states: California, Arizona, Colorado, Utah, and Nevada. I want to give you a bit of a preview of the kinds of places we will be visiting...
The Mojave National Preserve is one of our nation's newest parks (established in 1994). It was carved out from Bureau of Land Management lands in the eastern Mojave Desert, preserving one of the most awesome sand dune complexes in the country, the Kelso Dunes, a barren landscape of geologically recent volcanic cinder cones, one of the largest Joshua Tree forests in existence, and some of the highest mountain ranges in the Mojave Desert, with rocks as old as 1.7 billion years old, as ancient as those in the bottom of the Grand Canyon. The preserve also encompasses a California State Recreation Area, the Providence Mountains, and Mitchell Caverns, a unique limestone cave system. The caverns were closed during the recession, and then severely vandalized, but they have finally been reopened for visitation (see this Facebook page for updates).
One of the most interesting corners of the park is called Hole in the Wall, along with Banshee Canyon. We will be staying at the nearby campground our first night on the road on June 2. It is a wonderfully isolated spot, 25 miles off the main highway, and even farther from developments of any kind. It has some of the darkest night skies I've ever seen, and it is serenely quiet (except for crickets and coyote yowls).
The region is quite unlike other parts of the Mojave. Instead of deeply eroded mountain ranges and wide flat valleys, the area around Hole in the Wall is composed of mesas and plateaus that seem to share more in common with the Colorado Plateau province just to the east. But these mesas aren't like Arizona's either. They are composed not of sedimentary layers, but of volcanic tuff, rock derived from unimaginably huge volcanic explosions the likes of which modern humans have never experienced.
Twenty million years ago, the region was one of low relief, the result of tens of millions of years of erosion and relative stability. But conditions were changing as the crust was stretched and broken up into a series of tilted fault blocks. The release of pressure on the underlying mantle allowed partial melting to take place, and volcanic activity exploded across the region.
The first eruptions took place about 18.5 million years ago when the Peach Springs tuff coated the entire region from an eruption center near Oatman, Arizona. The eruption involved as much as 150 cubic miles (640 km3) of powdery white ash that was so hot that in many places it welded into solid rock as it landed.
Shortly afterward (in geologic terms anyway, as it was 700,000 years later), a second caldera developed. It was located even closer, in the adjacent Woods Mountains. The eruptive "crater", actually a collapse pit, was about 5-6 miles across, roughly similar in size to Crater Lake. Once again, all life was obliterated for hundreds of square miles as hot ash blanketed the landscape. The Wild Horse Mesa Tuff makes up most of the rock found at Hole in the Wall.
The strange holes that gave Hole in the Wall its name are called tafoni. Small differences in the degree of solidification or cementation cause depressions to form which end up staying wet longer, and the minerals decay into small fragments that can easily wash or blow away.
A short trail (1.5 miles) loops around Banshee Mountain and explores the best of the eroded tuff. Starting at the small visitor center, the trail drops through a rugged narrow canyon. There are some drop-offs, but rings have been attached to the canyon wall, making it a lot easier to climb up or down. Once past the narrows, the trail has a gentle gradient, and provides interesting views in all directions. There is a nice collection of petroglyphs on some of the boulders around the south end of the mountain.
If you want to visit this fascinating corner of the desert with us this June, please check out the previous post for details. We will be on the road for two weeks, and this will be only the first of many wonders that we will explore.

A Look Back at Ten Years of Geotripping: Time Beyond Imagining

I had no idea!

Almost ten years ago, on January 7, 2008, I posted the first entry on Geotripper. I had no idea where it would go, or how long it would last. A century, I guess, in blog years. I had not done a lot of writing before starting the blog, but I had a great many digital images to share, and some occasional stories to go with them. We will reach a couple of milestones this year, the 2,000th post, and possibly 3 million total hits, depending on how accurate Google counter is (Stat counter says 1.8 million). It's also been a wonderful opportunity to meet so many people from all over the world as they respond to posts. 

So...this week I am dredging through some of the archives to find some of my favorite posts from over the years. I'm starting with my first organized blog series on the geologic history of the Colorado Plateau, "Time Beyond Imagining". I began the series in July of 2008, and finished much later in October of 2009. There was enough material that I eventually compiled the story into a field guide I produced for the AAPG.

In any case, if you have any interest at all in the geology of the Four Corners region, and want to learn more about this fascinating landscape, check out the story below...

Time Almost Not Beyond Imagining: Recent Volcanism on the Colorado Plateau Pt. 3 The story of a stupendous rhyolite eruption at the Jemez Caldera in New Mexico

Time Almost Beyond Imagining: Who Do the Magic that Hoodoo? My favorite title for a discussion of a unique park near the Jemez Caldera, Kasha-Katuwe Tent Rocks National Monument

Time Almost Not Beyond Imagining: Recent Volcanism on the Colorado Plateau and Deep Time Although I had reached the last million years of a two billion year history, I felt a need to try and describe the immensity of geologic time, using the ruins of Bandelier National Park and the Jemez Caldera

Time Beyond Imagining - Where did the Ancient Enemy Go? The "disappearance" of the Ancestral Pueblo people is explored at Bandelier National Monument

Time Beyond Imagining: Why Can't We Touch the Venus de Milo? Once again, I thought I was done, but found a series of fascinating (to me) stories about research in the limestone caverns on the plateau. I began with a rant about preserving these wonderful caves that took us to Rome and Paris, of all places

Holy Crap, Batman! The Bat Cave is Full of it! Bat Cave in western Grand Canyon, and bat-sh*t. Lots of it, sort of

Holy Smokes, Batman, that crap is on fire! I was saving my best titles to the last, I guess. A horrific crime against science at Rampart Cave in the Grand Canyon


Time Beyond Imagining - A Final Struggle for Life on the Colorado Plateau I imagine the death of the very last mammoth on the Colorado Plateau

Time Beyond Imagining: The End of the Story, or the Beginning? In the final post of the series, I discuss the arrival of humans on the plateau, and how humans change the land they occupy. I also tip my hat to Ken Burns and his series on "The National Parks: America's Greatest Idea". The parks are the laboratories in which I and my students study the history of the earth.

So there you go: 71 posts that tell a story encompassing 2 billion years as it is exposed on a very special part of the earth's surface: the Colorado Plateau, covering parts of Arizona, Utah, Colorado, and New Mexico. Congratulations if you ever made it through the whole thing. I never realized I was writing the equivalent of an entire book, but it was a story I truly enjoyed telling, and I also deeply appreciated the feedback that many of you provided.

Bear's Ears Becomes a Reality! Now the Real Fight Must Begin

An incredible thing just happened, something I've always hoped for, but thought was well nigh impossible. The Bears Ears National Monument has become a reality! President Obama declared the monument under the authority of the Antiquities Act, which allows the president of the United States to protect endangered areas of cultural and natural importance.
Source: http://www.grandcanyontrust.org/bears-ears-national-monument-map
The new monument protects 1.35 million acres of the Colorado Plateau in southeastern Utah between the San Juan River and Canyonlands National Park. It includes one of the most significant archaeological regions in the United States, preserving a record of human occupation going back thousands of years. Mesa Verde National Park and Chaco Canyon National Historical Park and others preserve spectacular cliff dwellings and cities, but they are relatively small parks that cannot provide a full record of the human history of the region. Cedar Mesa and other parts of the Bears Ears country have long been recognized as a critical repository of knowledge regarding the comprehensive history of the Ancestral Pueblo people. Their descendants still live in the region to this day, and it is they who have perhaps pushed hardest for the monument designation. The reasons are obvious: the archaeological record and the cultural history of the people is in clear danger of disappearing forever. Their heritage is being plundered.
For years, local people have been destroying archaeological sites hunting for pots and other artifacts to sell on the black market. It's literally part of the local economy. It's incredibly illegal, but the rangers of the Bureau of Land Management are too few to patrol the vast region, and they and their families have been threatened with increasing frequency. It was a situation that needed to be changed, and the designation of the monument offers some hope that these sites could be better protected from desecration.

It may be hard for some people to understand how profoundly disturbing the attack on a people's heritage can be. Years ago, when I was on a raft trip on the San Juan River, the oarsman, a local resident, described how he had a mummified child hidden in his garage, not to mention a number of pots and arrowheads. A mummified child! Perhaps one can imagine finding graveyards across the United States plundered on a regular basis, by people seeking jewelry or gold teeth. Imagine finding that a the body of a deceased son or daughter was on display in someone's personal "museum". Those are the kinds of stakes involved here.
It's a strange thing. The vast majority of the people of Utah (and the rest of the country) have indicated support for the Bears Ears. The vast majority of the Native Americans in the region support the protection of the region. They've worked for years to plan the boundaries and administration of the park. Those opposed? The Republican Congressional delegation. The governor of Utah, and the state legislature. Why? They want the land given to the state of Utah to be sold off, for mining, for logging, or simply to be sold off for state funding purposes. They've called it a "land grab", but these are lands that belonged first to the Native Americans of the region, and later, to the American people through the federal government under the Bureau of Land Management. It does not belong to the state of Utah, and they have no true claim to it. This land needs to be managed for the good of all the people of the country, not the privileged few. The monument designation is the best approach, but it would be a greater idea for congress to declare the region a national park.
The news of the establishment of the new monument is thrilling to a great many people, but Barack Obama is president only for a few more weeks, and the power of the presidency is going to pass on to a man who is neither knowledgeable or appreciative of the value of this land to the many stakeholders in the monument. Trump only understands money and profit, and there is little doubt that his administration will try to remove the protections afforded by the monument designation. Therefore, we have a fight ahead of us. I hope that you will follow news about the monument and help protect it. The Southern Utah Wilderness Alliance is a good place to start. The Bears Ears Inter-Tribal Coalition is another good resource.
I haven't said much about my personal motivation for supporting this new monument. For years, I have been taking students into this region to learn geology and anthropology. I've spent many happy hours exploring the canyons and mesas, and regard the region to be the center of my spiritual universe. One could spend a lifetime here.
The Valley of the Gods (above) is a small version of Monument Valley (only a few miles north of the actual Monument Valley). The road that winds through the region is a marvelous excursion, but it is just one of many explorations possible in the region. There are also vast areas of wilderness, including the famed Grand Gulch, site of some of the most spectacular rock art in the entire southwest (not to mention the hundreds of cliff dwellings).
Cedar Mesa makes up much of the southern half of the monument. Views from the edge provide an incredible panorama of some of the greatest scenery in the United States. For years we have camped at the southern edge of the mesa, with views of Monument Valley, Navajo Mountain, the Goosenecks of the San Juan River, and the Rocky Mountains. These features are case studies for the understanding of erosional processes in arid regions. The rocks themselves preserve fossils and structures dating from the late Paleozoic era to the Mesozoic era, a time of advancing and receding seas. The fossil record includes all kinds of marine animals, and terrestrial creatures, including the dinosaurs and their ancestors.
President Obama will leave behind an legacy as one of the greatest environmentalists in our country's history. He has established nearly 30 monuments covering millions of acres, a heritage that protects long neglected landscapes that represent the best of our country. I'm hopeful that the politicians of Utah will finally come to realize the treasure that they possess (there is, after all, plenty of money that can be made from the proper promotion of parks and monuments). One can only dig up the coal or uranium once before the resource is lost forever, and the land is wasted more or less for all time. This new national monument is a gift that will last through coming time, while simultaneously preserving the heritage of a people from times past. And under all of it lies the abyss of geologic time, as preserved in the rocks themselves. It is a precious land.

Home From the Back of Beyond: Some Images of Strange and Wonderful Places

Thunderstorm near Bandelier National Monument
No, it's not a volcanic eruption, but with the light show that followed that evening, it might as well have been. We were in the high desert of New Mexico at Bandelier National Monument, and the monsoons had arrived early. The lightning flashed every second or two for hours that night. It was magical.
Joshua Trees outside of Rainbow Basin, Mojave Desert of California
I'm back from a long, but epic journey with my students through one of the most intriguing landscapes in North America, the Colorado Plateau. We crossed the California deserts to Arizona and New Mexico, swinging north through southwestern Colorado and southern Utah. Our last few days brought us through the Basin and Range Province of western Utah and Nevada.
Banshee Canyon in Hole in the Wall, Mojave National Preserve
As with all trips, I try to do new things whenever I can, but the real purpose was to open a different world to our students. This class was a hybrid course that explored the geology and archaeology of the region. It's a marvelous region for doing such a class, as humans have impacted the landscape, and the landscape has left its mark on humans.
The Citadel ruin and San Francisco Peaks from Wupatki National Monument, Arizona
The land has seen a parade of cultures over the centuries. Understanding why they abandoned the region in the past has a lot to do with understanding the limits of life there today. Sometimes the problems are the same. The Ancestral Puebloans may have left because of 25 year drought. We are in the midst of a 15 year drought today, although we experienced a very short reprieve from the dryness. A lot of ran fell in the weeks before our arrival. The desert was unusually green for this time of year.
Meteor Crater was impressive as always, a reminder that sometimes situations on our planet change in a hurry.
The Crystal Forest at Petrified Forest National Park, Arizona
Some of our stops were familiar to most people, such as Petrified Forest National Park. People may have heard of it, but many haven't visited. It's a bizarre landscape of badlands topography and horizontal forests of trees that wouldn't be out of place in the Redwood forests of California, yet are more than 200 million years old.
The slot canyon at Kasha Katuwe Tent Rocks National Monument
Other places are exceedingly obscure, although they don't deserve to be. Kasha Katuwe Tent Rocks National Monument is one of those places. Unless you are from Cappadocia, Turkey, it is one of the most unusual landscapes you'll ever see. The slot canyon is one of my favorite hikes anywhere.
The greenery was really pretty stunning after fifteen years of crippling drought. The drought is not broken by any means, but the rainy conditions over the last few weeks allowed us to imagine this landscape under a different climate regime. At Chaco Culture National Historical Park, the rangers described the plant growth as the most intense they had ever seen. The elks wandering near the campground were looking downright fat (of course the doe was probably about to drop a calf).
Chaco Canyon represented the height of the political power of the Ancestral Puebloans, in the period around 1150 AD. By the 1200s they were building the fortresses of the cliff-dwellings in Mesa Verde. It wasn't the culmination of their society, but the prelude to abandonment. Whatever the reason, the canyons fell silent around 1285. The people had migrated south and east into the Hopi mesas area and the riverlands of the Rio Grande in New Mexico.
Cliff Palace in Mesa Verde National Park, one of the largest of the cliff cities.
One of our stops was especially eerie. Castle Rock was one of the last of the Ancestral Pueblo dwellings to be constructed. It came to an end after only a decade or two with a massacre. Archaeologists discovered more than three dozen slaughtered people in the excavations.
Castle Rock, in Canyons of the Ancients National Monument
The last part of our trip went back to the geological aspects of the plateau country. Despite having visited the Natural Bridges National Monument nearly two dozen times over the years, this was the first time I was able to hike under Sipapu Bridge, probably the second largest natural bridge in the world. The opening is more than 200 feet high, and from the bottom, it is immense. Those are mature cottonwood trees in the picture below!
Sipapu Bridge in Natural Bridges National Monument
We made the very hot hike to Horseshoe Bend near Glen Canyon Dam on the Colorado River. An entrenched meander, the loop formed when the land rose, trapping a river in its floodplain pattern. The stunning cliffs are composed of the Navajo Sandstone, the remnants of a Jurassic-aged sand dune "sea" that once covered many western states.
Horseshoe Bend, near Glen Canyon Dam. The Colorado River runs clear because the dam has captured the silt that once gave the river its name. Algae is able to thrive in the clear water.
The culmination of the Navajo Sandstone is found at Zion National Park in southern Utah. The Virgin River has carved an incredibly deep slot canyon at the Narrows. In many places the river fills the entire valley floor, meaning a hike is a wet affair. I didn't hesitate!
So, I am home for a couple of days, and will try to pick up the pace with a few long-delayed blog entries. You can certainly expect more information from our last couple of trips in the plateau country as well! It's good to be home for a spell.
