Carlton County
Carlton County is the heart of Minnesota's inland agate country: glaciers dragged Lake Superior agate south and dumped it in the region's thick gravel deposits, and the nearby Moose Lake area is billed as the Agate Capital of the World. Agate turns up in the county's gravel pits, gravel roads, and river cuts around Cloquet rather than on a single outcrop. Carlton County runs a formal agate-picking permit program that opens designated county pits to collectors.
