This is Driftless bluff and karst country, where loess sits over limestone and sandstone. Thin soil on the ridges and deep valleys both change what a base course has to do.
Ground Conditions Across Olmsted County
Across the Driftless bluff and karst country, loess lies over residual soil on Paleozoic limestone, dolostone and sandstone. The layer is thin on the ridge tops and deep in the valleys, with rock outcrops on the bluffs and little or no glacial drift.
A thin base over that ground shows its failure fast. Traffic works the material loose and the surface ruts and potholes instead of holding together.
The fix is a compacted Class 5 course over the subgrade, thick enough to spread the load. That is where the base depth question starts.
Water here runs off steep slopes quickly and then disappears into sinkholes and fractures rather than soaking in evenly. Surface flow is flashy, valley floors flood fast, and a downspout run aimed at a sinkhole goes straight to groundwater.
Drainage rock and clear rock belong anywhere water needs to move away from a structure. Keeping flow off a slope also matters, because rill and gully erosion cut into steep loess ground after heavy rain.
The working season runs from the thaw into late autumn, one of the longer ones in the state. Spring load limits go up on Southeast zone roads in early March and come off in April.
Frost lifts slabs and walks on the thin, silty soils over rock, and the freeze-thaw cycle repeats through the winter. The Minnesota Residential Code footing table sets 3 feet 6 inches for its Zone II counties.

Choosing the Right Material
Winona County shares this ground region, so the soil, the karst drainage and the erosion pattern are the same there as they are here. The base and drainage choices carry over unchanged.
Mower and Dodge counties sit on gray, calcareous Des Moines lobe till, loamy to clayey and carrying shale, under deep black prairie soil. That is a very different subgrade from loess over limestone.
On till ground, water moves through the soil more slowly and the base sits on a heavier, more uniform subgrade. On karst ground, water vanishes into fractures, so drainage rock and clear rock do work that a fines-bearing base cannot.
