Landscape
Small intermittent and perennial first order streams drain into and through a chain of four dimictic lakes. The annual hydrograph is dominated by spring snowmelt. The forest is predominantly mature to over mature tolerant sugar maple with some yellow birch throughout. The watershed is on the Pre-Cambrian Shield. Thin to absent glacial tills overlay greenstones with some granite. Soils are spodosols developed from bouldery silt loam ablation tills overlying less permeable compacted basal tills.
