Pea Gravel and Bulk Aggregates for Sheridan, MT
Montana Rock Supply handles gravel and aggregate delivery in Sheridan, MT, by the ton or by the yard. Crushed base course is the standard base material here, and it is what most drives, shop pads and parking areas in Madison County start from.
Sheridan sits in a mountain valley where the ground runs gravelly in places and clay-rich in others. That mix decides which material a job needs.
Materials for Sheridan Projects
Water is the reason washed stone matters here. Snowmelt and summer storms both arrive fast, and a drain that clogs with fines stops working.
Washed rock, also called drain rock or 3/4 clean, has the fines washed out, so it stays open in a French drain, a curtain drain, a drywell or a downspout run.
Washed rock is the coarse end of the drainage sizes. 3/4" Crushed Stone works for drainage beds, pipe bedding and construction entrances, and 3/8" Crushed Stone is a finer drainage and trench bedding stone.
#57 Stone and #67 Stone are specified locally by inch size more often than by number.
For the base itself, 3/4 Crushed Base Course is the Montana standard, usually ordered as 3/4 minus. Pit run is unprocessed pit gravel for deep fill and raising grade under a base, not a finished driving surface.
Driveway Gravel, or road mix, carries enough fines and clay binder to pack hard on a county-style lane.
Finer material has its own jobs. Crusher fines, which Montana yards call screenings, bed pavers and flagstone and surface packed pathways.
Washed Sand levels and beds under flatwork and pavers. Mason Sand goes into brick and block work and paver joints.
Decorative and soil products round out a yard. Yellowstone River Rock fills decorative beds and dry creek beds, and Large River Rock takes the heavier erosion and splash work.
Top Soil and Garden Soil cover lawns, grading and raised beds over thin or stony native ground.

Ground and Conditions in Sheridan
The working season here is short. Base, driveway and paver work runs from late spring into early autumn on the valley floors, and shorter again on higher ground.
Timing a delivery around that window matters as much as the material choice.
Across the Southwest and south-central mountain valleys, the ground is a mix. Gravelly alluvium and outwash sit on some basin floors, clay-rich basin fill sits on others, and thin stony soils cover the ranges that ring them.
Gravel takes water readily; clay-rich fill does not.
That difference shows up in drainage. Snowmelt off the Great Divide, sudden summer thunderstorms on dry ground and irrigation ditches crossing valley floors all put water where it has to go somewhere.
A clean washed stone drain handles it; a fines-bearing material does not.
Spring runoff and bank scour are the other local driver, along with gullying and debris flows off burned slopes. Riprap armors stream banks, culvert outlets, coulees and ditches against that.
Frost heave in drives and roads is a normal condition at these elevations, not only a spring event. Hard overnight freezing with a daytime thaw runs through much of the year.
Footing depth is set by the local building department.
