Only one wetland each was mapped as D34 and D43, neither was visited. These are small peatlands in bedrock depressions not hydrologically connected at or very near the surface with other wetlands. They have a deeper water table and a forested or woodland component (D4) mixed with a shrubby component (D3). They were both mapped on the bedrock knob north of Bear Lake.
