The Last Christmas Gift: A Joshua Tree

A last Christmas scene...

Some of my family lives in the desert near Joshua Tree National Park. We hadn't been there in the past, and expected one of those California-style cookie cutter housing developments imposed on a desert landscape that doesn't really reflect the nature of the desert. Arriving late in the day, I was delighted to find that there was an unspoiled Joshua Tree forest adjacent to their lot. The sun was setting, so I took off across the desert to get a few pictures.

Joshua Trees are a species almost unique to California (I think a few spill over into Arizona and Nevada), and they are a semi-tropical holdover from a different climate and ecosystem. Their seeds do not have a readily available method of dispersal so the tree isn't invading new habitats as the climate grows warmer. It has been suggested that prior to 13,000 years before the present their seeds were spread by giant ground sloths, who were known to eat the fruits of the tree. No animal performs the task today.
The tree got its name from the early Mormon colonizers in the region, who likened the branches to the arms of Joshua of the Bible raised in prayer. They are a unique part of the flora that defines the Mojave Desert.

Have a good Christmas night!

These photos are fantastic! Joshua Tree National Monument is one of my favorite places, but I was unable to take pictures while I was there. So thanks for reminding me just how epic those trees are!

Joshua Tree truly is beautiful country. I love their shapes rising up high above the desert floor. We do have some joshua tree forests in AZ. I didn't know about the lack of seed dispersal. Surprised some humans haven't tried to reseed it. Haven't been there in way too long.
You've had a wonder Christmas vacation.

There are a number of lovely Joshua Tree "forests" in the Beaver Dam Mts. and the Virgin River gorge on I-15 between St George UT and Mesquite NV. Most of them would be considered strictly to be in NW AZ but definitely bleed into Utah too - great hiking here.

That 1st shot is GREAT! What an amazing place. Love it's kooky magic.

Joshua was signaling an attack on the enemy city of Ai, following God's command: "Stretch out the javelin that is in your hand toward Ai; for I will give it into your hand." I don't think there's anything prayerful about the attitude of Joshua trees.
