Wisconsin Point: Lake Superior Agate & Jasper Rockhounding in Douglas County, Wisconsin
Updated July 2026
Wisconsin Point, a three-mile public sand and gravel spit at the mouth of Superior Bay, is the state's most accessible Lake Superior agate beach. The agates are wave and glacially transported nodules of banded chalcedony weathered from the billion-year-old Keweenawan basalts, and the strand line also yields jasper, drift copper, and basalt. The point is owned by the City of Superior and open to the public, with collecting best along the gravel lenses after storms and at low water. Reported finds include lake superior agate, jasper, copper, basalt. Below: coordinates, access notes, nearby spots, and trip-planning links.
