Road Mix, Sand and Gravel Delivery in Power County, ID
If you are planning a driveway, a shop pad or a drainage run, Idaho Rock Supply handles gravel, stone and aggregate delivery in Power County, ID. Most of that work starts with road mix, the crushed base Idaho yards sell with the fines left in so it locks up under a roller.
From American Falls down through Rockland and Arbon, ground here runs from thin soil over young basalt to deep valley alluvium in the Bear River country. That difference decides how much base goes under a drive and where drainage rock belongs.
Materials delivered in Power County
Road mix is the base course under driveways, parking pads, shop floors and shed slabs. Contractors often ask for the same load as 3/4 minus, and it is the same material either way.
On public works plans around here, base is written as crushed aggregate in Type I and Type II under the Idaho Standards for Public Works Construction, Section 802, and uncrushed aggregate under Section 801.
State highway work follows the ITD Standard Specifications, where Section 703.04 covers aggregate for untreated base, treated base and road mix, including the 3/4 inch minus gradation, and Section 703.11 covers granular subbase. Those are how material is specified in Idaho.
Beyond the base, yards here carry Fill Dirt for backfill and bringing a low spot up, Mason Sand for brick and block work and paver joints, and 3/8" Natural Pea Gravel for patios and play areas. Natural Pea Gravel is round and uncrushed, so it rolls underfoot where angular chips knit together and stay put.

Ground conditions across Power County
Power County spans more than one ground region, and the difference shows up under a base course. In the upper Snake River Plain and the eastern farm valleys, young basalt flows sit close to the surface with thin soil over them, so drives and footings rest on shallow ground over rock.
Water is the other half of it. On the plain, basalt near the surface leaves water nowhere to go, and canal seepage and heavy spring irrigation lift the water table under low farmed ground.
A thin base over ground like this shows the same failure: soft spots, rutting and edges that break down at the spring thaw. A drainage layer of clean rock under the wrong material makes it worse, because fines migrate into open stone and it stops draining.
Erosion runs on the same pattern. Spring runoff off the Caribou and Centennial ranges and wind moving dune sand and dry field soil on the plain, with canal bank and culvert washouts during snowmelt.
Timing matters as much as material. On the plain, frozen ground stops compaction from late fall to early spring, and the dependable base and paver window runs from late spring into early autumn.
Valley work runs from the spring thaw into the fall, with a shorter window in the higher valleys. Around Pocatello and the southeast valleys, about 30 inches is the frost depth figure commonly used, and the local building official sets footing depth.
Choosing the right material
Cassia County, over in the Magic Valley, sits on a thin blanket of loess and wind-laid silt loam over fractured basalt, with rock often within a few feet of the surface.
That is shallower ground than the deep valley alluvium in parts of Power County, so a drive there runs into rock sooner and drainage has less soil to move through.
Bingham County shares Power County's upper Snake River Plain ground, so the basalt, the thin soil and the river sand and gravel are the same story. Bannock County shares the Southeast Idaho valleys and Bear River country ground, with the same loess over limestone and sandstone and the same gravel fans at the canyon mouths.
Match the material to the ground, not to the label. Road mix for a compacted base, drain rock where water has to move, and pit run only as sub base, structural fill or hole filling.
