Mount Konocti, a composite dacitic volcano, rises above the southern shore of Clear Lake. The arcuate escarpment facing the lake on the the NW-most peak, Buckingham Peak (right), is a landslide scarp produced when part of the dome collapsed. A series of maars cuts the southern shore of Clear Lake, giving it a scalloped shoreline. Clear Lake itself, the largest natural freshwater lake entirely within California, is an elongated, irregular body of water more than 30 km long. It has a volcano-tectonic origin.
