The uplands surrounding these soils are commonly acid sands. The Greenwood soils are deep organic soils. The Kinross and Roscommon soils are poorly drained or very poorly drained sandy mineral soils commonly near the edges of the Dawson soils or as inclusions within the Dawson soils where the organic deposit is less than 16 inches thick. Very poorly drained. The depth to the seasonal high water table ranges from 1 foot above the surface to 1 foot below the surface from September to June.
Surface runoff is very low or negligible.
Permeability is moderately slow to moderately rapid in the organic material and rapid in the sandy mineral portion. Very little commercial use is made of these soils, because of the extreme acidity, shallowness of the organic deposit, and the high water table. Tree vegetation is sparse with black spruce and tamarack comprising the major species. Ground cover is composed of bog rosemary, cranberries, laurel, leatherleaf, sphagnum mosses, and blueberries. Northern part of the Lower Peninsula and Upper Peninsula of Michigan, Wisconsin, and Minnesota.
