Research Natural Area

Keeley Creek

State: Minnesota

County: Lake

Forest: Superior

District: Kawishiwi

Established: 1942

Acres: 640

Description: The RNA contains forests that typically regenerate in northeastern Minnesota after wildfire. The last major fire in the RNA is believed to have occurred about 1870. Upland forests are primarily jack pine (Pinus banksiana), with black spruce (Picea mariana) dominating the lowland peat bogs. Rock outcrops are also present. The mature forests are the RNA’s distinguishing feature.
