North Cascades National ParkThis is some of the spectacular scenery found on the northern edge of Washington State in North Cascades National Park.The rocks in this area are a faulted-up jumble of everything that makes up the Rocky Mountains. There are sandstones and limestones, products of the times when the western U.S. was inundated with water, rocks from volcanic arcs that slammed into the U.S. coast, and even more recent lavas from the modern day cascades. Carved by glaciers during the recent ice ages into sharp peaks, this remote area makes for foreboding but lovely photos like this one.-JBBImage credit: NPShttps://www.flickr.com/photos/northcascadesnationalpark/3567861756/in/set-72157621956489126More:http://geomaps.wr.usgs.gov/parks/noca/nocageol1.html -- source link
