Historical/Interpretive Information/Exhibits

Located on the Historic tour route there is a very large boulder, forty feet in length, twenty feet in height and eight feet wide.  In the early 1800’s cave visitors called the huge, rectangular boulder the “Steamboat”.  By the 1840’s, guides and visitors alike, decided the rock looked more like a Giant’s Coffin, the name is still used for this boulder on the Historic Tour route today.  You will also find historic signatures located on this large boulder.
