Cornwallis' Cave, in Yorktown, VA. This cave was carved by man and presumably used by the British General Cornwallis to hide from colonial forces during the Siege of Yorktown. It is situated in the Yorktown Formation, a geologic unit that formed from fossiliferous sand during the Miocene. Cross-beds are evident in this photo, and have been measured to dip to the northwest at 24 degrees.
