Lincoln County is covered by thick glacial drift, lakes, marshes and forests, thus bedrock exposures are sparse. It is underlain by a complex mix of granitic rocks, meta-volcanic and meta-sedimentary rocks. These were deformed during the Penokean Orogeny, a continent-to-continent collision event occurring about 1.8 billion years old. Caught up in these are several massive sulfide deposits that have been prospected geophysically and by drill coring. A few outcrops of meta-sedimentary rocks yield interesting metamorphic minerals. The glacial drift may yield specimens to the determined collector, including drift copper, "Lake Superior" agates, placer gold and perhaps a drift diamond or two.
