Here's hoping your holiday was a "transformative" experience! In honor of the concept, I present a Friday Fun Foto: What mountain is this?
A couple of clues: It is the southwesternmost peak in the United States that shows evidence of Pleistocene glaciation, maybe even the southernmost, period, and also has the southernmost grove of Aspen trees in the United States. As far as the "transformative" part, in the picture above, not one, but two strands of the San Andreas fault lie tucked between the ridges visible in this photograph.
Merry Christmas and happy holidays to all! Thanks to Susan Hayes for the photo.
UPDATE: As Chasmanian Devil and Forrest noted, it is San Gorgonio Peak, the highest mountain in Southern California at an elevation of 11,499 feet. The mountain shrunk three feet over the course of my life, as I grew up in SoCal with the highest point being officially 11,502 feet. It got too heavy, or else the surveying methods improved! San Gorgonio is a fascinating place to hike, especially if you like wilderness: many people follow the trails to the summit, but some wonderful lonely trails explore the flanks of the peak, especially at the headwaters of the Whitewater River. It was glaciated in the Pleistocene ice ages, and recent research has established the precise glacial chronology. It even has a few natural lakes, a rarity in southern California mountains. It's a place I am anxious to get back to! I highly recommend a book by Stephens Press called Call of the Mountains, a beautiful photo-essay about southern California's mountains.
