Whipstock HillThis spectacular road cut is found in Vermont near the boundary with New York. The rocks originally formed as sediments along the eastern coast of Laurentia; the continent that composes most of North America today. These rocks started off as limestones, forming in warm and shallow waters in the Iapetus Ocean. Eventually, the crust of the Iapetus Ocean began subducting out at sea, forming an island arc that ran into the continent, causing a pulse of mountain building known as the Taconic Orogeny. That mountain building caused these rocks to be metamorphosed, turning them into marbles and forming the folds.A pattern of an anticline and a syncline, as seen here, occurs when a layer of rocks basically buckles. As the rocks are pressed from the side, they shorten and fold up and down if there is little resistance in those directions. You can simulate this kind of folding just by squeezing a few layers of paper; on their own they will buckle both up and down unless you put a solid layer beneath the paper.-JBBImage credit: James St. Johnhttps://flic.kr/p/dCH5UmReferences:http://bit.ly/1Vwwjp9http://bit.ly/1Vwwjpkhttp://venturing4th.blogspot.com/2014/06/whipstock-hill.html -- source link
