That does seem like quite an anomaly. I did a little research, and it appears that Yosemite MAY have been covered with a small continental glacier, such as an ice cap at some point during the Pleistocene.So I came back from Yosemite a few days ago. It was really interesting to see glacially carved troughs, but what surprised me the most was that there is a roche moutonnee in the park! It's name is the Lembert Dome. I thought they were only formed by continental glaciers, and I'm pretty sure there weren't any in California during the most recent Ice Age... does anyone have an explanation for this? Can they be formed by valley glaciers too?
I don't have access to any Earth Science college or high school textbooks (I am in middle school).
