Devonian Shale in Upstate New York
April 11, 2007
Shown here is an outcrop of Devonian shale in upstate New York. Shale is a very soft, erodible rock, and thus is seldom seen in fresh outcrop exposures like this one. More often, shale outcrops are slumped, weathered or covered by upslope sediments. This particular shale is rich in organic matter, hence the dark gray color. Photo taken on April 28, 2006.
