Jeffers Petroglyphs, near Comfrey in southern Minnesota, is one of the most significant rock-art sites in the Midwest — an exposed ridge of red quartzite carved with thousands of sacred images by the ancestors of today's Native American peoples. It is a living spiritual place, not a museum, and the Minnesota Historical Society cares for it in partnership with Native communities. For RV travelers crossing the prairie, it is a chance to stand quietly before some of the oldest art in the region.
Best season — Late spring through early fall (check MNHS for current open season)

On the ground
The Minnesota Historical Society describes the site as holding about 5,000 sacred rock carvings — petroglyphs pecked into a long outcrop of hard red quartzite that rises out of the surrounding prairie grasses. The agency frames these as among the oldest carvings in the Midwest.
This is a sacred place to Native American peoples, and the respect it asks for is simple and non-negotiable: stay on the established trail, do not walk on or touch the carvings, and never attempt rubbings or castings. Oils and pressure from hands damage rock art permanently — these images cannot be replaced.
Come with a leave-no-trace mindset. Take only photographs and leave only footprints, give other visitors quiet space, and treat the ridge as the living heritage it is. Always confirm the current season, hours, and any guided-tour requirements on the Minnesota Historical Society site before planning your route.
