Red Wing: Lake Superior Agate Rockhounding in Goodhue County, Minnesota

Updated July 2026

Red Wing anchors the southeastern reach of Minnesota's Lake Superior agate range: glaciers and the Mississippi River spread agate-bearing gravel far south of the stone's North Shore origin. Collectors work the gravelly bars, banks, and river-mouth deposits along the Mississippi for banded agate, and the region's Paleozoic bluffs add fossil interest. The stones here are the same billion-year-old rift agates found up north, redeposited by ice and water. Reported finds include lake superior agate.
