Hemlock Cliffs (GM-14)
Hemlock Caverns is one of the numerous caves found in that area. Indian artifacts have been found in Indian Cave and Arrowhead Arch, a 160-foot tunnel through the sandstone bluff. Two deep, circular holes in a large tablelike rock near the west end of the tunnel apparently are Indian grain-grinding relics. The scenic features of Hemlock Cliffs are well worth being seen by Hoosier citizens.
