Crushed base course is the material both kinds of work usually come down to. It is the standard Montana base, locally called 3/4 minus or 3/4 crushed base course.
Ground Conditions Across Cascade County
Ground here runs from deep silty and clayey prairie soils on the benches to gravelly terraces and shallow stony ground up in the island ranges. On the Central Montana benchlands and island ranges, clay subgrades soften as soon as they wet up.
A thin base over clay shows it first as rutting and pumping at the edges. Spring snowmelt running across ground still frozen underneath makes it worse.
Wind erosion on open ground and gullying on silt and clay slopes both move material you paid to place. Riprap and large river rock armor banks, culvert outlets, coulees and ditches against that.
Work runs from breakup into autumn, and the benchland dries out quickly once runoff is past. Cold inland winters cut by chinooks freeze, thaw and refreeze the ground, which softens gravel roads each time it cycles.
Materials Delivered in Cascade County
3/4 Crushed Base Course is the standard Montana base material, usually ordered by top size as 3/4 minus. In Montana, base material is specified as crushed base course under MDT Section 701.02.4, with grades named by nominal top size.
Grade 5A is 2 inch minus and Grade 6A is 1 1/2 inch minus, with a 3/4 inch minus grade, 7A, developed as pit sources for the larger sizes ran short.
City and county work is more often written against Section 02235, Crushed Base Course, of the Montana Public Works Standard Specifications. County road standards call sizes out the same way, as 3 inch minus sub-base and 1 inch minus crushed base or top course.
Use crushed base course for driveways, shop pads, parking areas and shed bases. Pit Run is unprocessed pit gravel for deep fill and raising grade, not a finished driving surface.
Driveway Gravel, or road mix, surfaces a drive or a county-style lane. It carries enough fines and clay binder to pack hard once rolled.
Washed Rock, called drain rock or 3/4 clean, is washed so the fines are out. It goes in French drains, curtain drains, foundation drains and downspout runs.
3/4" Crushed Stone is clean crushed rock for drainage beds, pipe bedding and construction entrances. Stone Screenings, or crusher fines, bed pavers and flagstone and surface packed pathways.
For planting and finish work, Top Soil is screened for lawns, grading and bed prep, and Yellowstone River Rock covers decorative beds and dry creek beds.

Choosing the Right Material
Lewis and Clark County is in Southwest Montana and its valleys differ enough from the benchlands here that the base and drainage choices differ with them. Teton County shares Central Montana with Cascade County but runs wetter and heavier in its clay stretches.
Chouteau County ground is slow-draining in a way that pushes drainage rock higher in the order.
