Finger Lakes State Park

Finger Lakes State Park occupies a reclaimed coal strip mine near Columbia in Boone County, central Missouri. Missouri State Parks manages the site as one of only two ATV oriented parks in the system, with off road trails, a motocross track, campground, swimming beach, and the 3.8 mile Kelley Branch Mountain Bike Trail winding through wooded hills above finger shaped pit lakes.

For mineral collectors, the interest is secondary sulfate minerals formed when pyrite in mine waste and shale weathers in contact with air and water. Mineral locality records list aragonite, copiapite, gypsum, halotrichite, marcasite, melanterite, and pyrite from the park. These are typical products of acid mine drainage chemistry on disturbed ground, often ephemeral and fragile.

Missouri state park regulations prohibit digging, removing, or disturbing beach sand, gravel, minerals, soil, rock, or artifacts without written permission from the state parks director. That prohibition is explicit in 10 CSR 90-2.040 and applies to submerged and exposed material alike. You may observe mineral coatings on cut slopes and pit walls, but nothing may be taken. Finger Lakes is a recreation and geology viewing destination, not a collecting site.

Match your visit to your activity. ORV riders need permits, approved safety gear, and awareness of same day online permit rules. Hikers and mountain bikers use Kelley Branch and lakeside paths without an ORV permit.

If you are interested in mine geology, study cut slopes and pit lake exposures from established trails and roads. Bring a hand lens and camera, not hammers or collecting bags. Sulfate efflorescence changes with weather and may disappear after rain.

Timing: spring through fall for trail comfort. Facilities: campground, beach, boat ramp, picnic areas, ORV staging areas.

For legal Missouri collecting, research other localities on private land with permission or public agencies with different rules. See other Missouri collecting areas such as the geode streams of northeastern Missouri.

Central Missouri's Boone County coal field fueled local industry through much of the twentieth century. Strip mining reshaped this landscape into the pit lakes and berms visitors see today before the state reclaimed the site for recreation. Converting an industrial mine into a state park is unusual in the Midwest. Finger Lakes now draws ATV enthusiasts from across Missouri while also serving Columbia residents with mountain biking, paddling, and camping minutes from town.

Reclaimed mine land erodes quickly when users leave established routes. Stay on trails and ORV designated tracks to limit slope damage and sediment runoff into pit lakes. Removing rock or sulfate crusts destroys fragile mineral specimens that reform only under specific weather conditions. Report illegal collecting to park staff. Collectors seeking Missouri minerals should work on land where removal is actually permitted.
