Jeffers Petroglyphs Site - Credit: Wikimedia Commons
The Jeffers Petroglyphs site is an outcrop in southwestern Minnesota with pre-contact Native American petroglyphs. The petroglyphs are pecked into rock of the Red Rock Ridge, a -long Sioux quartzite outcrop that extends from Watonwan County, Minnesota to Brown County, Minnesota. The exposed surface is approximately and surrounded by virgin prairie. "The site lies in an area inhabited in the early historic period by the Dakota Indians, and both the style and form of some of the carvings are identical with motifs that appear on Dakota hide paintings and their quill designs and beadwork. Others are foreign to this Plains Indian tradition and seem to be much earlier in origin." Several old wagon trail ruts traverse the site, one of which is believed to be the old stage coach route from New Ulm, Minnesota to Sioux Falls, South Dakota.Roefer Read more on Wikipedia
