Views From Powers Bluff

These views are looking north and northeast down the ski runs, which are the only open areas in the park.

The Quartzite

The rock here is very different from most of the other quartzites of Wisconsin. Most "Baraboo Interval" quartzites are sugary in texture and range in color from white through pink to maroon. The Powers Bluff quartzite is massive and very glassy (and is called chert in some descriptions) and is variegated in color, with black, red, and white predominant. Bedding is indistinct and mostly steeply north-dipping. The bedding is mostly revealed by color banding and there is no mechanically distinct layering.

Outcrops on Bluff Road
