The western half of the County is part of the driftless (non-glaciated) region of Wisconsin. This area is mostly rolling hills and valleys (known locally as coulees) and is scattered with dairy farms. The land that is too steep for farming is primarily oak forest. Nearly all land in the western half of the County is privately owned. The east half and west half of Jackson County are divided by the scenic and wild Black River. For 10 miles, before reaching the County Seat of Black River Falls, the Black River winds its way through a channel cut into the red granite bedrock. Each side of the river is lined with granite boulders and mature white pine forests. This stretch of the river has almost no development until you reach the City of Black River Falls.
