Example of a landscape dominated by roche moutonnée: Tuolumne Meadows in Yosemite National Park, Sierra Nevada, USA
Roche moutonnée is a land form created by glacial erosion. The "grinding" and "polishing" of a glacier creates a wavy surface of bedrock, which is often covered with other spores of glacial erosion, such as striations. Roche moutonnée develops best when the bedrock consists of a hard lithology like gneis or granite.
The wavy structures are usually of the order of a few meters and asymmetrical in diameter. The side in the direction in which ice flowed earlier is usually steep, the side against the flow is rounded, more or less analogous to the asymmetry of fluvatic flow ribs.
