Outcrops in and near Interstate Park expose Keweenawan (1.1 billion year old) basaltic lava flows, unconformably overlain by Cambrian sandstone, shale and conglomerate. The St. Croix River, fed by huge surges of water from draining glacial lakes to the north, has cut a deep gorge, with gigantic world-class pot-holes carved into the hard basalt. Several small copper mines were sunk in the volcanic rock west of town, with little production, in the late 1800's, early 1900's.
