Are there pictographs at Pictured Rocks?
No pictographs (rock paintings) or petroglyphs (rock pecking) have been discovered within the Lakeshore’s 42 miles of Lake Superior shoreline. Because the Lakeshore’s friable sandstone bedrock is relatively soft and large collapses of rock occur annually, it is unlikely that any rock paintings that may have been done in the past have survived. Pictographs are more common in Minnesota’s boundary waters region and in adjacent portions of Canada. An impressive panel of pictographs is a feature of the human history of Lake Superior Provincial Park in Ontario.
