Minnesota Northwoods Sand Plains, Bogs & Canadian Shield Margin
Dominant Soil Order: Spodosols / Entisols / Histosols / Inceptisols
Parent Material: Glacial Outwash Sand, Lacustrine Silt, Peat and Muck over Glacial Drift and Precambrian Bedrock
Northern Minnesota is the wet end of the state: outwash sand plains, extensive peat bogs, and the granite-greenstone Canadian Shield bedrock of the Arrowhead. Ground conditions split three ways. Sand-plain counties cut fast in loamy sand but stand poorly, so trench boxes are standard. Bog and wetland counties (Clearwater, Beltrami, Lake of the Woods, Koochiching) carry hydric soils on 40-70 percent of land, muck excavation and peat removal are ordinary site work, and water tables run within inches of grade. The Arrowhead counties (St. Louis, Lake, Cook) add the state's only shallow bedrock: Precambrian greenstone, basalt and the Duluth Complex lie within 50 inches on 20-60 percent of land, so rock excavation and blasting appear in most utility bids, with frost reaching the deepest design values in the contiguous states. Shrink-swell is negligible everywhere. The compressed building season concentrates excavation between May and October.
Geographic Footprint:Minnesota's northern tier (the Arrowhead, the sand plains north of Brainerd, and the Red Lake bog country) is sand, peat and Precambrian rock: fast-cutting sands, heavy muck work, and the state's only blasting. The season runs May through October.

Area-specific FAQ
Do I need to call before digging in Wadena County?
Yes. You should contact Gopher State One Call at least 2 working days before any digging so underground lines can be marked.
How deep do footings need to be in Minnesota?
In Minnesota, footings typically need to extend below the frost line, which is around 100 inches here. A local contractor will confirm the code requirement for your site.
