Geology of Connecticut - River Valley

River Valley

This soft surface has since been downcut, resedimented and oft flooded by the Connecticut River, making it a very soft, nutrient-replenished area and host to the majority of Connecticut’s farmland soils. The land on either side of the Connecticut River Valley is less suitable for farmlands. The eastern section holds the shallow Proto-North American Terrane while the western section contains the Iapetos and Avalonian Terranes, which still holds remnants of glacial till and lack the soft fluvial sediments so prominent in the Connecticut River Valley region.
