Geologically spectacular narrow gorge cut by the Licking River; excellent display of spring wildflowers.
The prime feature of this preserve is a narrow east-west gorge cut by the Licking River through the famous Black Hand sandstone formation. It also boasts the only bike trail in Ohio's state nature preserve system. More than 4 miles of bike trail wind through the preserve.
The name Blackhand, for which the preserve is named, originated from a dark hand-shaped Indian petroglyph that was engraved on the face of a massive sandstone cliff along the north side of the river. The engraving was destroyed in 1828 when canal builders dynamited the cliff face, during construction of the Ohio-Erie Canal, which runs through the gorge. Sections of the canal towpaths and canal locks can be seen from the trails along the river.
The dry hilltops are dominated by oak-hickory mature woods along with Virginia pine and mountain laurel. Yellow birch, cherry birch and eastern hemlock grow on northerly exposures. It is an excellent site for viewing woodland spring wildflowers.
The preserve is rich in natural as well as early Ohio history.
