One of the few places Cambrian rocks are exposed in northeastern Wisconsin. Low ledges occur in the stream west of the culvert on 39th Road, just north of Highway 64. These are fairly well indurated pure coarse sandstones. The generally friable nature of the Cambrian sandstones and the fact that the recessional moraines lie above the Cambrian outcrop belt combine to make Cambrian outcrops very rare in this part of the state.
