Williamson Rock is under a temporary closure to all recreational uses, including climbing, pursuant to a ruling by the U.S. Fish and Wildlife Service that the area is critical habitat for the endangered yellow-legged mountain frog.

The Ego Buttress is the tall broad wall, left of the Sick Wall. This wall is home to a dozen 5.10 - 5.12 routes. The Ego Buttress is south facing and thus can be a warm destination on cooler days.
