This is Coteau des Prairies ground, a high plateau under deep glacial till. That shapes what you put down and what you bring in.

Materials for Iroquois Projects

Grading and bed prep start with soil, not stone. Stony loam over dense till leaves little real growing layer, so lawns, raised beds and shelterbelt pockets here begin with material hauled in.

Top Soil is screened black dirt for lawns and bed prep. Spread it where the native ground is too thin or too stony to plant into.

Garden Soil goes into raised beds, vegetable ground and planting pockets. It gives roots a workable layer above tight till.

Fill Dirt raises grade and backfills. Build a pad up to level before any base course goes down on top of it.

Once grade is set, Base Course takes over. It is the crushed base layer, and it carries driveways, parking pads and shop slabs.

Gravel Cushion is the cushion course rolled out under concrete and asphalt and the crushed top course on a gravel drive. It finishes to a stable surface rather than a set density.

For drainage, Washed Rock is the clean stone for drain tile, drywells, sump and downspout runs, and window wells. It is the usual Dakotas word for clean drainage stone.

Sand and decorative stone round out the list. Mason Sand beds brick and block, fills paver joints and works as play sand.

River Rock holds decorative beds and borders where wind makes bark mulch a losing battle.

Ground and Conditions in Iroquois

Water is the driver here. Closed pothole basins across the Coteau des Prairies have no outlet, so snowmelt and spring rain sit until they soak away or evaporate.

The dense till under the topsoil takes water slowly. Yards and drive edges stay wet long after the surface looks dry, and that soft ground will not hold a load.

Runoff from snowmelt and thunderstorms cuts ditches and drive edges on the coteau slopes. Wind scours bare open ground.

Riprap and heavier stone at culvert outlets and low edges slow that cutting.

Frozen ground stops compaction, so base, driveway and paver work runs from the spring thaw into late fall. The frost boil weeks in early spring are the worst time to place material.

Winters bring deep frost, repeated freeze-thaw and drifting. Gravel drives heave through the winter and soften badly when the frost comes out.

Frost depth in the northern counties is commonly 42 to 48 inches, and the local building official sets the figure that applies.

What stone should I use for drainage in Iroquois?

Washed Rock is the clean stone for drain tile, drywells, sump and downspout runs, and window wells. It carries water instead of holding it, which matters on dense till where water moves slowly.

For heavier drainage, #4 Crushed Stone is a larger clean rock for trench bottoms in wet ground.
