Glacial Erratic at Monthey
The house on the rock was built on an isolated massive boulder. The rock is composed of Mt. Blanc granite, which is not found near this region, and obviously had to be transported for many kilometers by action of glaciers.
RMNP
Rocky Mountain National Park --- The valley has been carved by glaciers between the viewpoint from Trail Ridge Road and the string of peaks in the distance along the Continental Divide. Longs Peak, the only 14,000 foot peak in the park, is the flat-topped mountain in the far distance.
Roche Mountonné at Gorner Glacier
Smooth mounded rocks called roche moutonné (sheep rocks) formed by the action of the Gorner Glacier on the crystalline basement of the Monte Rosa Nappe. Note the striations on the rocks in the lower left corner.
