Lineage

Very high sensitivity: The characteristics of areas rated as very high are bedrock at or near the land surface and shallow karst units with identified sinkholes. The areas with bedrock at the land surface are shown on Plate 3, Part A. The areas with cover less than 25 feet thick are shown on Plate 5, Part A. Both of these bedrock characteristics mostly occur within the shallow karst hydrogeomorphic units described on Plate 10: Cedar River plain, Deer Creek plain, Le Roy plain, Ostrander plain, Spring Valley plain, and Le Roy upland.

High sensitivity: Areas of high sensitivity include the Limestone plain karst unit (see Plate 10), except where cover is less than 25 feet thick, which is rated as very high.

Moderate Sensitivity: Areas of moderate sensitivity in Mower County occur in two situations: A large deposit of sandy outwash in western Mower County, and areas in the Covered karst unit with till less than 75 feet thick.

Low Sensitivity: Areas mapped as till on Plate 3 with more than 75 feet to bedrock (Plate 5) are rated as low sensitivity>
