Roche Moutonee, a glacial erosional feature, Yosemite National Park.
Lembert Dome in Yosemite is a Roche Moutonee, a bedrock feature sculpted by glacial erosion. In this photo (view roughly eastward), the ice flowed from right to left, abrading the gentle side of the roche moutonee and plucking bedrock pieces from the steeper side as it flowed away from it. Lembert Dome lies in the Tuolemne Meadows part of the national park.
