Rainy Lobe ground moraine and end moraines form the eastern line. This subsection is a real mix of end moraines, outwash plains, till plains, and drumlin fields. White and red pine dominated the majority of forest communities on end moraines and till plains. Jack pine barrens and jack pine woods were found on well drained sites on outwash plains. Black spruce, tamarack, white cedar, and black ash were prominent tree species in poorly to very poorly drained soils.
Lakes are very common on the end moraines and some of the outwash plains.
Current landuses include tourism, forestry, and some agriculture. The moraines are relatively large and were formed from portions of several glacial lobes. Most of the glacial drift was sandy, but there is loamy drift to the north. Thicknesses range from 200 to over 600 feet. There are also iron formation at the southeastern edge of the subsection, along with argillite, siltstone, quartzite, and graywacke.
