| Landscape Narrative |
General Landscape Description: Remarkable marl deposits (up to 50 feet deep) exist around the periphery of White Lake. The lake occurs in a pre-pleistocene karst valley with a glacial till-dam at the lake outlet on the south side. Piggyback Pond is a solution sinkhole in the karst watershed with dramatic seasonal water level fluctuations. Land use history shows evidence of agriculture, lgging and mining.
Soil Comments: Tried to dig hole for piezometer. Clay to 8' where encountered water but water dissapeared from hole (possibly drained). Heavy clay with distinct mottles. No plant organic matter.
Soil Texture: Mineral - silty clay
Landscape Setting: Solution valley, collapsed delta plain.
