Burton Township Land Use Plan - 7Ba Outwash

7Ba Outwash

This hydrogeologic setting is characterized by the rolling, hummocky, "kame and kettle" topography primarily associated with the Kent Kame Complex and Kent Moraine. Outwash deposits include ice-contact derived kames, depressional kettles and bogs, outwash plains, and channeled outwash valley trains associated with the stagnation of the Late Wisconsinan Kent Till. Outwash deposits typically overlie buried valleys: in some areas they overlie fractured sedimentary rocks. These deposits contain varying amounts of till and finer silt deposits that may somewhat impede recharge. Sands and gravels serve as the aquifer: the nature and extent of such units is highly variable. Recharge is moderate to high and soils are typically loams or sandy loams with peat or clay occurring in the depressions and kettles. Water levels are highly variable but generally range between 20 and 40 feet. The depth to water is greater for the prominent kames and is usually shallower near kettles. These deposits may be in direct hydraulic connection with underlying, fractured bedrock.
