Cassville Bluffs State Natural Area

Cassville Bluffs

This 244-acre bluffland farm had served as a nature retreat for the Roe family for over 50 years.  Cassville Bluffs State Natural Area (CBSNA) was conserved through a joint effort by the Mississippi Valley Conservancy and the Wisconsin DNR.  MVC owns 190.6 acres and the Wisconsin DNR owns the remaining 53 acres (primarily the bluffland goat prairies and savannas along the River.)

CBSNA contains a variety of habitats including upland and lowland oak-hickory forest as well as the rare savannahs and goat prairies overlooking the Mississippi River. 

The property also is home to a falcon effigy mound with a 270-foot wingspan that was constructed by Native Americans roughly a thousand years ago.
