Stone commonly used in Montana includes granite, limestone and sandstone. Orders are delivered by dump truck to jobs from the Yellowstone River, the Flathead Valley and the Gallatin Valley, with delivery included in the price.
Common projects here include ranch roads, 3/4 minus driveways and shop and barn pads. East of the divide it is gumbo clay that turns to grease when wet and sets like concrete when dry; west of it the valleys are alluvial gravel that drains. Both freeze four feet down, so the base depth is not negotiable. Frost goes to about 48 inches in Montana, so plan base depth around it.

Testimonials from Customers
Customer Comments
“One ton of mason sand for the kids' sandbox and to level a few pavers on a small patio near Broadus. Fine and clean, with hardly any clumps, and the grandkids have been digging in it all summer without a single complaint about rocks underfoot.”
Regina U.
Mason Sand
“Two yards of garden soil for a new vegetable garden bed near Huson in the valley. Montana Rock Supply had it delivered within two days of ordering. Rich and dark, mixed with compost already, and the tomatoes and squash have done better this year than any summer since we started gardening out here.”
Lloyd G.
Garden Soil
“Needed something smaller than river rock for a fire pit patio out near Ennis and this fit the bill at five tons. Doesn't scatter as bad as true pea gravel once it settles in, stays put under the chairs, and the color is a nice even gray that matches the stone on the house.”
Eugene P.
#89 Crushed Stone
“We regraded a steep driveway for a client outside Columbia Falls that climbs hard enough it used to wash out every time snowmelt came off the mountain fast. Twenty two tons of three quarter went down as the base layer, locked together tight under the compactor, and topped with a finer gravel a week later. Through this spring's runoff and a summer of thunderstorms the grade has held with zero washout, which is the first time in three years the owner hasn't had to regrade before the Fourth of July. Tri axle handled the narrow approach better than I expected for a truck that size.”
Lois K.
3/4" Crushed Stone
“Six tons for a short driveway base out near Chester that used to pothole every spring thaw. Locked in solid after one pass with a rented compactor, and it hasn't shifted since despite a wet June. My husband was skeptical it would hold under the truck, but it has.”
Cheryl D.
Pit Run (Crusher Run)
“Used at a culvert crossing that kept washing out every spring near Joliet. Fifteen tons later the ditch holds its shape through heavy runoff instead of eroding back toward the road. Driver dumped it right along the bank where we flagged it.”
