Hemlock Cliffs (GM-14)
Hemlock Cliffs is an 840-acre plot in southwestern Crawford County. Some of the land is privately owned, and the rest lies within the Hoosier National Forest. Deeply and precipitously dissected sandstone bedrock (early Mississippian in age) forms large hemlock-fringed gorges in several places.

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.
