River Rock, Stone and Soil Delivery in Florence, MT
Montana Rock Supply handles gravel and aggregate delivery in Florence, MT, and the ground here shapes what you order. Across the Western intermontane valleys, silt and clay left by Glacial Lake Missoula sit on the valley floors, and that fine ground drains slowly and stays soft well into spring.
Crushed base course, the 3/4 minus this market builds on, is where most drives and shop pads start. On silt, the base has to carry the load the soil underneath cannot.
Materials for Florence Projects
Water is the practical problem on this side of the valley. Lake-bed silt drains slowly, so roof runoff and spring melt have to go somewhere, and washed stone is how that gets handled.
Washed Rock, also called drain rock or 3/4 clean, has the fines washed out. That is the whole point for French drains, curtain drains, foundation drains and downspout runs, where water needs open void space rather than a material that packs tight.
3/4" Crushed Stone is a clean crushed rock for drainage beds, pipe bedding, construction entrances and surfacing over a compacted base. A size down, 3/8" Crushed Stone suits fine drainage, trench bedding and a tight topping.
#57 Stone is specified for drainage, French drains and concrete aggregate, and Montana yards more often quote it by inch size than by number.
For drywells and downspout work, Large River Rock gives you rounded stone with open space around it, and it also handles splash pads and dry creek beds.
Where the ground is thin and stony, Top Soil is screened for lawns and bed prep, and Garden Soil goes into raised beds and planting areas where native clay or gravel will not do on its own.

Each product page has a calculator if you want to size the load before you order. A dump truck then tips the material on your site in one pile.
Ground and Conditions in Florence
The working season here runs from breakup into late fall, which is long enough by Montana standards. The catch is that silty valley ground has to dry out before it will compact, so timing a delivery matters as much as the material.
Snowmelt off the surrounding ranges keeps the rivers up through May and June, and that is when bank scour and gully cutting do their damage. Riprap is the material for stream bank and culvert outlet armoring, ditch protection and slope work against spring runoff.
Valley winters bring hard overnight freezing, inversions that pool cold air on the floor, and chinook thaws that cycle the ground and heave gravel surfaces. Around Missoula, about 36 inches is the frost depth figure commonly used, with deeper figures at higher elevation, and the local building department sets footing depth.
