Natural Features Description:

This small fen wetland natural community is surrounded by xeric soils on a steep hillside. Historically this fen was maintained as an opening due to the saturation of the soil and periodic wildfires that burned through adjacent glades and woodlands. Characteristic fen plants include umbrella grass, swamp loosestrife, winged loosestrife, cowbane, and waxy meadow rue. This fen occurs on a series of ledges formed of dolomite of the Gasconade Formation.
