Bulk Gravel and Stone Delivery in Park County, WY
Wyoming Rock Supply handles gravel, stone and aggregate delivery in Park County, WY. If you are building a driveway, setting a pad for a shop, or bedding a patio, the job starts with crushed base.
That is the material this state builds on, and it is what you order by name here.
Crushed base is also called 3/4 minus or road base, and it is the compacted layer that carries a drive, a parking area or a county-style lane. Around Cody, Powell and Meeteetse the ground underneath is alkaline silt and clay over shale, so what you put on top of it matters.
Ground Conditions Across Park County
Park County sits in the Bighorn Basin, the driest ground in the state. The lower basin takes only 5 to 8 inches of precipitation in a year, so most of the water that reaches your site arrives as snowmelt or as irrigation.
That changes where drainage work goes. Water shows up in a rush from ditch and canal flow, from cloudbursts on bare clay, and from ground that seals over instead of soaking it in.
Plan the drainage layer before you plan the surface.
The soil is alkaline and saline silt and clay over Cretaceous shale, with gypsum and bentonite beds in the mix. Bentonite is the one to watch: it swells when it gets wet and moves under a load, so a surface laid straight on it will not stay put.
Winters here are cold and dry, with far less snow than the mountains around the rim. Bare frozen ground and deep frost are normal, and thaw cycles work directly on unprotected surfacing.
No published frost depth figure was found for Park County, and the local building department sets footing depth. Ask there before you plan anything structural.
Wind is the other force at work. On bare, dry, sparsely vegetated ground it strips fines and cuts sheet and gully erosion along irrigation runs.
The working season on the warm basin floor is comparatively long by Wyoming standards, running from spring breakup well into autumn.
Materials Delivered in Park County
Crushed base is the standard Wyoming base material. In this state it is specified as crushed base.
Grading W is the common one-inch-top-size base and Grading GR is the 3/4 inch gradation. City and county work is usually written against Section 02190 of the Wyoming Public Works Standard Specifications, which uses the same grading letters and states that base shall be crushed base unless otherwise specified.
Order it as crushed base or 3/4 minus for driveways, shop and shed pads, parking areas and county-style lanes.
Washed stone covers the clean drainage side. 3/4" Crushed Stone is a clean crushed rock for drainage beds, pipe bedding and construction entrances.
3/8" Crushed Stone is a finer clean rock for trench bedding and a tight topping over a compacted base.
Sand and soil round out the order. Mason Sand goes into brick and block work and paver joints.
Washed Sand levels and beds under flatwork and pavers. Garden Soil fills raised beds where native clay or basin sand will not do on its own.
For decorative work, Wind River Rock is rounded river-washed stone for beds, borders and dry creek beds, and Large River Rock takes the heavier erosion and splash work under downspouts.

Choosing the Right Material
Ground conditions in this part of Wyoming are shared with Big Horn County and Washakie County, which sit in the same Bighorn Basin ground region. The soil, the low precipitation and the drainage problems are the same across all three, so the base and drainage choices do not change at the county line.
Teton County is the real contrast. It sits in Jackson Hole, the wettest and snowiest corner of the state, and it is the only part of Wyoming where drainage design usually assumes plenty of water.
Ground there is glacial outwash, till and cobbly river gravel, with deep silt and clay and a high water table on the Salt River bottoms through Star Valley.
Here the assumption runs the other way. Alkaline clay and shale seal over instead of soaking, so drainage rock and a compacted crushed base do the work that abundant rainfall does elsewhere.
Washed rock, riprap and Crushed Stone matter more when water arrives in a rush and has nowhere to go.
