Last week Callan Bentley decided to go digging through some old images and his action inspired me to do the same. Fortunately for me, I knew exactly the purpose of the images I had set aside. I took this picture with my iPhone while flying back from the AGU Meeting in San Francisco last December, and was struck by the saw-tooth appearance seen in the landscape.
What I am describing as “saw-tooth” appearance are the eroded V-shaped notches in the bedrock and the snow. Using what a professor of mine described as the “Power of Geomorphology” we can infer a few things about this landscape. The orange annotated notches below all point to the left side of the picture indicating that the homoclinal ridges are dipping the same direction. The fact that the same phenomena is shown in the snow covering is just a nice added bonus.
Highlighted in blue is the dendritic drainage pattern indicating that the melt channels are working their way into a homogeneous material, in this case snow, and heading down slope to the east (since I was facing south when I took this picture…I think).
