Moxham Mountain Exfoliation
April 23, 2003
The above photo shows the snow-covered face of an exfoliated dome, Moxham Mountain, located about 5 miles northeast of North Creek, New York. In this case, exfoliation, an "onion-like peeling" of massive granitic rocks, occurs through a combination of pressure-release and weathering. This rock dome had originally formed at some depth below the surface. See also yesterday's Earth Science Picture of the Day.
