What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone has angular, broken faces, so it bites and locks when compacted. That is why 3/4 inch crushed rock works as drainage beds and pipe bedding over a compacted base. Natural Pea Gravel is rounded and washed, so it stays loose and moves underfoot. It suits walkways, play areas, dog runs and drainage where rounded stone is wanted.

Should I order material by the ton or by the yard?

Both work, and the choice is mostly about how you think about the job. Order by the ton when you are working from weight, and by the yard when you are working from volume. Each product page has a calculator, so you can size the load before you check out. Quantities are ordered in either unit.

Across the Eastern plains, Missouri Breaks and badlands, bentonite-rich gumbo clay weathered off marine shale decides how a project goes. It swells and turns greasy when it wets up, so water sits on the surface instead of draining away.

Ground Conditions Across Big Horn County

Water is the driver on this ground. Gumbo clay swells and turns greasy as soon as it wets up, and it cracks open again when it dries.

Rain, snowmelt and summer cloudbursts cannot soak in, so they run off the surface. On unsurfaced ground that means soft roads and ruts, and in the badlands it means fast gully and rill cutting in shale and clay.

Erosion shows up as slumping along the Missouri Breaks and bank scour on the rivers that cross this part of the state. A compacted base course and a clean drainage layer are how you keep water moving instead of standing.

Timing matters as much as material. Work follows dry ground, because spring breakup and heavy rain make gumbo roads impassable.

Midsummer and early autumn are the dependable window.

Winters here are cold and dry with deep frost and wide day-to-night swings. Ground that thaws on a chinook afternoon and refreezes overnight heaves gravel roads and opens up drives.

Published frost depth figures across Montana run from about 36 to 60 inches, and eastern plains figures are usually quoted at the lower end. The local building department sets footing depth.

Materials Delivered in Big Horn County

Base material in Montana is specified as crushed base course, covered under Section 701.02.4 of the MDT Standard Specifications for Road and Bridge Construction. Grades are named by nominal top size, so Grade 5A is 2 inch minus and Grade 6A is 1 1/2 inch minus.

City and county work is more often written against Section 02235, Crushed Base Course, of the Montana Public Works Standard Specifications, and county road standards call sizes out the same way.

Crushed base course is the workhorse. It goes down under drives, shop pads, parking areas and shed bases, and it takes the traffic that would otherwise cut straight into gumbo.

Riprap handles the erosion side: stream bank and culvert outlet armoring, coulee and ditch protection, and slope work against spring runoff. Fill Dirt raises grade before a base course goes down, and Washed Sand levels and beds under flatwork and pavers.

Bulk material arrives by dump truck and tips in one pile where the truck can reach. Nothing is placed or spread, so have the spot clear and reachable before the truck arrives.

Choosing the Right Material

Big Horn County shares its ground region with Rosebud County and Powder River County: bentonite-rich gumbo clay weathered off marine shale, badlands, scoria beds and broken Missouri Breaks ground. The ground is the same, so the same reasoning holds.

Yellowstone County is different. Its ground runs to river terrace sand, gravel and cobble, silty loam bench soils, shale-derived clay on the rims, and shallow stony ground.

Where the ground drains more freely, water moves through instead of sitting, and a clean washed stone can carry the drainage. On gumbo, a compacted crushed base course matters more, because the clay holds water at the surface.
