Helderberg Escarpment

I caught this picture last weekend when I went apple picking. It was taken looking south towards the Helderberg Escarpment west south-west of Albany. Here is a better description:

The Helderberg Escarpment is the northeasternmost extent of the Allegheny Plateau at its juncture with the Interior Lowlands and the Hudson Valley. This juncture is responsible for the dramatic cliffs which rise over 305 meters (1,000 feet) from the valley floor. The Helderberg Plateau consists predominantly of layers of shale, sandstone, and limestone. Water flowing through the layers of limestone on the plateau has dissolved and eroded the rock, leading to a geological landscape known as karst terrain that includes several caves. Because the exposed cliffs are rich in fossils, chronicling a half-billion years of geological history, it has intrigued paleontologists and geologists for years. For an in depth report about the area go here.
