Mount Sopris

From Wikipedia: "Mount Sopris is believed to have been formed by an igneous intrusion 10,000 feet below the Earth's surface, geologically referred to as a pluton, that occurred around 30 million years ago, after the initial uplift of the modern Rocky Mountains. Mount Sopris is not a volcano, but it is possible that an ancient volcano sat above it, with the current rock forming the magma chamber far below. Due to subsequent continued erosion, any evidence is now gone. In either case, the rock that makes up Sopris never reached the surface, cooling and crystallizing in situ, and later becoming exposed due to erosion."
