Bulk Material Delivery in Alta, WY

Wyoming Rock Supply handles gravel and aggregate delivery in Alta, WY, and the ground here sets the plan. This is the wettest, snowiest corner of the state, where glacial outwash and cobbly river gravel sit beside deep silt, so two lots on the same street can drain nothing alike.

That is why crushed base is the starting point for drives, shop pads and parking areas, and why washed stone matters just as much once snowmelt starts moving.

Materials for Alta Projects

Water is the driver on this side of the state. Snowmelt off a heavy pack has to go somewhere, so drainage work here is not an afterthought.

Washed rock, also called drain rock or 3/4 clean, is the material for perimeter and curtain drains, foundation drains and downspout runs.

Washing the fines out is the whole point. Clean stone lets water through instead of silting up, and a drywell or a French drain built with it keeps working season after season.

Around that drainage work, the rest of a project follows in sizes.

• Washed Rock for perimeter drains, foundation drains, downspout runs and drywells.
• RipRap, or armor rock, for stream bank and culvert outlet armoring, ditch lining and slope protection against spring runoff.
• Crushed Base, the local name for 3/4 minus or crushed base course, for driveways, shed pads, parking areas and county-style lanes.
• Pit Run, unprocessed pit gravel, for deep fill and raising grade under a crushed base course.
• Stone Screenings, also called crusher fines, for paver and flagstone bedding and packed pathways that need to hold together in wind.

For a tighter finish, 3/8 inch crushed rock, or chip rock, works as a fine drainage layer and a topping over a compacted base. Natural Pea Gravel and Wind River Rock suit walkways, dog runs and decorative beds where rounded stone is wanted.

Topsoil and garden soil cover the planting side. Native ground here is thin, stony and often alkaline, so yards routinely bring in screened topsoil for lawns, grading and bed prep.

Delivery to Alta and the Surrounding Area

Ordering runs online. You choose a quantity by the ton or by the yard, and each product page has a calculator if you want to size a load before you commit.

Pick your delivery date at checkout and a dump truck tips the material on site in one pile. Wyoming Rock Supply delivers across Teton County, including Jackson, Wilson, Kelly, Moose and Moran alongside Alta.

Bulk loads are heavy and the truck needs room to reach the spot you have in mind. Have the drop area clear before the date arrives.

Ground and Conditions in Alta

The working season is the shortest in the state. Snow holds the ground into late spring and the window for base, driveway and paver work is squeezed at both ends, so timing a delivery matters as much as the material itself.

Frost is deep and long-lying, with ground staying frozen under snow cover well into spring and then releasing all at once. Design frost depth for footings in Teton County is a figure the building official or a soils engineer sets for the site.

What that means in practice is that base depth and drainage get decided before anything is ordered. On ground where coarse outwash meets slow silt, a drive that drains poorly will not hold up through a melt, no matter how good the surface looks in July.

Erosion is the other half of it. Spring high water scours banks, and fast runoff off steep fan ground cuts rills on slopes before they revegetate.

RipRap and clean stone are how those edges get armored.
