Materials delivered in Sheridan County
Crushed base course is the standard Montana base material, usually ordered by top size as 3/4 minus. In Montana it is specified as crushed base course, covered by the MDT Standard Specifications under Section 701.02.4.
Those grades are named by nominal top size: Grade 5A at 2 inch minus and Grade 6A at 1 1/2 inch minus, with a 3/4 inch minus grade, 7A, developed for MDT. City and county work is 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.
Sand, fill and mulch round out the list. Mason Sand goes into brick and block work and paver joints.
Washed Sand levels and beds flatwork and pavers.
Fill Dirt handles bulk fill and backfill before a base course goes down, and Shredded Mulch dresses beds and tree rings. Shredded bark holds on slopes and in wind better than nuggets, which matters on open ground.
Choosing the right material
Roosevelt County and Daniels County sit on the same ground region as Sheridan County. Glacial till over shale, a mix of clay, gravel, sand and silt left by the ice and by glacial lakes, much of it heavy and slow-draining, with coulee and river-bottom alluvium cut down through it.
Across the Hi-Line and the northern glaciated plains, the ground does not change much from one county line to the next. The material choice follows the same logic: a compacted base where you drive, clean washed stone where you drain.
Start with what the surface has to do. Crushed base course carries traffic and locks up under compaction.
Road mix surfaces a lane and packs hard. Washed rock drains, because the fines are washed out.
Pit run is unprocessed pit gravel for deep fill and raising grade, never a finished driving surface. Crusher fines bed pavers and pack into a path.
Rounded stone goes where you want a bed or a border, not where you need structure.
Ground conditions across Sheridan County
Water drives everything here. Snowmelt sits on subsoil that is still frozen, and a semi-arid year breaks open with a few intense summer storms.
Flat ground and heavy till drain slowly, so where the water goes decides the design. A drainage layer of washed rock moves it away from a foundation or a downspout instead of letting it pond.
Wind strips bare ground, sheet and gully erosion cut through the coulees, and banks get cut along the larger channels. Riprap armors a culvert outlet, a ditch or a slope against spring runoff.
The working season is short. Frost is in the ground from late autumn into spring, and compaction waits for it to come out.
Chinook thaws cycle the surface without taking the frost fully out until spring.
Winters run cold, with deep frost and long cold spells. Footing depth is set by the local building department.

Questions about gravel and soil in Sheridan County
What is the difference between topsoil and fill dirt?
Topsoil is screened and holds the organic matter and texture that seed and plants need, so it goes on lawns, beds and graded areas. Fill dirt is bulk material for backfill and raising grade under a base course or a slab.
Put fill down first, then topsoil over it where you want growth.
What is crushed base course and what is it used for in Sheridan County?
Crushed base course is crushed stone graded by nominal top size, usually ordered as 3/4 minus. In Montana it is specified under MDT Section 701.02.4, with Grade 5A at 2 inch minus and Grade 6A at 1 1/2 inch minus, and city and county work written against Section 02235, Crushed Base Course.
It builds driveways, shop pads, parking areas and shed bases.
How deep should a gravel driveway base be in Sheridan County?
Depth depends on your ground, the traffic it carries and how the site drains, and there is no single figure that fits every drive here. Heavy till and slow drainage change what a drive needs compared with well-drained ground.
Size your material on the product page calculator once you know your area and the depth you are building.
