Ground Conditions Across Fergus County
Fergus County sits on the Central Montana benchlands and island ranges. Deep silty and clayey prairie soils cover the benches, and gravelly terraces run along the Judith and Musselshell.
That clay does the damage. It softens as soon as it wets up, so a thin layer of rock punches straight through under a truck tire.
Spring snowmelt makes it worse. Water runs across ground that is still frozen underneath, and it has nowhere to go.
Heavy summer thunderstorms on open benchland do the same thing in an afternoon. Wind moves the bare farmland soil, and silt and clay slopes gully where runoff concentrates.
The answer is a thicker, better-graded base course over a drainage layer, not a skim coat of rock. Work runs from breakup into autumn, and the benchland dries out quickly once spring runoff is past.
Cold inland winters cut by chinooks freeze the ground hard, then thaw and refreeze it. Gravel roads soften and rut every time it cycles.
Frost depth in Great Falls is commonly figured at about 42 inches, with deeper figures in the ranges; the local building department sets footing depth.
Materials Delivered in Fergus County
Crushed base course is the base material in Montana, and it is specified that way.
The MDT Standard Specifications cover it under Section 701.02.4, where grades are named by nominal top size: Grade 5A at 2 inch minus and Grade 6A at 1 1/2 inch minus, with 7A at 3/4 inch minus 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.
For a drive, a shop pad or a shed base, order 3/4 Crushed Base Course as 3/4 minus.
Fill the rest of the list from the same yard. Fill Dirt handles bulk fill and backfill before a base course goes down.
Washed Sand levels and beds flatwork and pavers, and acts as concrete sand. Mason Sand covers brick and block work, paver joints and play sand.
For planting, Garden Soil fills raised beds where native clay or gravel will not do on its own. Shredded Mulch dresses beds and tree rings, and shredded bark holds on slopes and in wind better than nuggets on open ground.
Delivery Across Fergus County
Order online and a dump truck tips the load on site. Choose tons or yards, whichever your numbers are already in.
Each product page has a calculator for sizing the load.
Pick your delivery date at checkout. The truck arrives and tips the material in one pile.
Delivery covers Lewistown, Moore, Denton, Winifred, Roy, Grass Range, Coffee Creek, Forest Grove and Hilger, plus the surrounding benchland and island range country.
Have the drop spot clear and reachable before the truck arrives. A bulk load is heavy, and soft ground after breakup will not hold a truck.
Choosing the Right Material
Fergus County shares its ground with Judith Basin County, Wheatland County and Petroleum County. All three sit on the same Central Montana benchlands and island ranges, with the same deep silty and clayey prairie soils, the same gravelly terraces and the same shallow stony ground on the island ranges.
The ground is the same across all four, so the base and drainage choice does not change at the county line. Pick by the job in front of you.
