Take an expert-led tour of the petroglyphs (rock carvings) that are thought to be some of the oldest in the Midwest. You will get the rare chance to go beyond the ropes and view carvings under their most favorable viewing conditions: up close and in the morning sun.

Glaciers had retreated from Southwest Minnesota 10,000 years ago, opening up never-before seen landscape. This tour will be accompanied by a discussion of the archaeology of the earliest people of the Midwest and the climatic and environmental conditions they would have faced in this era.

Plan to arrive at least 10 minutes earlier than the event start time.
