Viola Rockshelter

January 31, 2019

Viola Rockshelter PetroglyphsThe Viola Rockshelter is partway up a small ravine in the bluffs that form the deeply cut Kickapoo River Valley in Vernon County, Wisconsin. A petroglyph panel at the site has three groups of figures, including the human figure and possible dwelling pictured here. Salvage excavations in 1986 found four periods of occupation ranging from ca. 1500 BC to AD 1000. The relationship between the petroglyphs and the occupations is unknown.
