Glacier County, MT Gravel and Landscape Rock Delivery
Montana Rock Supply handles gravel, stone and aggregate delivery in Glacier County, MT. The base material here is crushed base course, the same 3/4 minus that contractors in this part of Montana order by top size.
Ground across the Rocky Mountain Front runs from gravelly glacial till and outwash near the mountains to deep clay and silty prairie soils farther out. That mix decides what goes under a drive and what goes around a foundation.
Ground Conditions Across Glacier County
Work in this part of Montana runs from breakup into autumn. Spring thaw and steady wind shape how a site drains and how long bare ground stays workable.
Fast runoff comes off the front at snowmelt, and upslope storms stall rain against the mountains. Prairie clay sheds that water instead of taking it in, so water moves across a site rather than down through it.
Wind on open ground and flash runoff in the creeks coming off the front both cut at banks and bare soil. Riprap and mulch both answer that.
Chinook country means long cold spells break under warm downslope winds that can lift temperatures fast. The ground thaws and refreezes through the winter instead of staying frozen, which is hard on a base that was never built to shed water.
Materials Delivered in Glacier County
Crushed base course is the standard Montana base material, and it is what most drives, shop pads, parking areas and shed bases are built on.
Montana specifies base material as crushed base course under MDT Standard Specifications 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 3/4 inch minus, Grade 7A, 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.
Choosing the Right Material
Pondera County sits on the same Rocky Mountain Front ground as Glacier County. Gravelly glacial till and outwash near the mountains grade into the same deep clay and silty prairie soils, with cobble alluvium on the creek bottoms.
The ground is the same, so the base and drainage choices are the same.
Toole County is different. It sits on the Hi-Line and the northern glaciated plains, where glacial till over shale leaves a mix of clay, gravel, sand and silt left by the ice and by glacial lakes.
Much of that is heavy and slow-draining, with coulee and river-bottom alluvium cut down through it.
That difference matters for drainage. Ground that holds water needs a clean washed stone layer to move it, while ground that sheds water needs a base built to stay put under runoff.
