Kelsey Beach: Lake Superior Agate Rockhounding in Lake County, Minnesota
Updated July 2026
Kelsey Beach, the public cobble beach at the Stewart River mouth a few miles north of Two Harbors, sits in the North Shore agate belt where wave-sorted gravel yields Lake Superior agate along with basalt and jasper from the billion-year-old rift lava flows. Like the rest of the shore, it produces best after storms wash fresh cobbles onto the beach. A small highway pull-off and short foot paths give straightforward public access away from the busier marquee stops. Reported finds include lake superior agate. Below: coordinates, access notes, nearby spots, and trip-planning links.
