| 説明 | This granite dome has a long, gentle side on the right and a short, steep side on the left. It formed by glacial abrasion and plucking. Such glacially eroded knobs of bedrock are called roches moutonnées. The long side is the up-glacier side. The short side is the down-glacier side (= the direction the glacier was moving).The rocks are porphyritic granodiorites.Geologic unit: Cathedral Peak Granite, mid-Late Cretaceous 86-88 MaLocality: Lembert Dome, Yosemite National Park, California, USA-------------------------------See info. at:en.wikipedia.org/wiki/Roche_moutonnéeanden.wikipedia.org/wiki/Lembert_Dome |
