Honors College
The C horizon is the deepest soil layer that is technically unweathered, similar to the rest of the regolith beneath the bottom of the pedon. In New England, the C horizon formed from the retreat of the glaciers eroding bedrock and depositing an unsorted and unstratified glacial till on the surface. This research evaluated the hydrologic and chemical role of the C horizon, inclusive of underlying regolith, in a forested watershed at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire. Results suggest that the C horizon at HBEF is extensive and heterogeneous. Traditional concepts of basal till offer a …
