A single diverse wetland was mapped as SA, a discharge slope dominated by alders. The wetland lies along a slope, where shllow groundwater discharges to near the surface, north of Bear Lake. A little over half of the wetland is a wet forest with alder and devil's club openings along the slope. The other smaller portion is a flat peatland at the top of the slope.
