Where on Earth? - September 2011

Clues for September 2011:
1. This glacially sculpted ridge tops out at about 3,500 meters, roughly 640 meters above the lake of the same name seen in the foreground. The rock is predominantly Cretaceous-aged granodiorite, an intrusive igneous rock found throughout the national park that hosts the ridge, including at some better-known monoliths nearby.
2. The south-to-north knife-edge traverse along the ridge provides a popular but challenging trail for climbers, many of whom set out from a busy campsite known for its seasonal “tent city.”
3.  The ridge was named for a Dutch-born engineer and geologist who, while working for the U.S. Geological Survey in the early 20th century, became one of the pre-eminent experts on the glacial activity that shaped the area where this feature is located.

Answer: The glacially sculpted ridge of Matthes Crest rises to 3,500 meters, about 640 meters above Matthes Lake in the foreground. The rock is predominantly Cretaceous-aged granodiorite, found throughout California’s Yosemite National Park and comprising nearby monoliths such as Half Dome. The ridge was named for Francois Matthes, a Dutch-born engineer who in the early 20th century became one of the pre-eminent experts on the region’s glacial activity. Photo is by Paul Riley.
