Soil Regime ProfileEPA Ecoregion 18, 17, 25, 34 (Wyoming Basin, Middle Rockies, High Plains, Northwestern Great Plains)

Wyoming High Plains, Basin-and-Range & Central Rockies

Dominant Soil Order: Aridisols / Mollisols / Inceptisols / Entisols
Parent Material: High Plains Ogallala Gravel and Caliche, Cretaceous Shale Badlands, and Crystalline Core Uplifts with Glacial Mountain Fill

Wyoming is high-plains basins between crystalline ranges, and the excavation profile is rock-forward. The basins (Powder River, Green River, Wind River, Great Divide) sit on Tertiary sediments and Cretaceous shale: sandy and clayey aridisols over Ogallala gravel and caliche in places, bentonitic shale in the badland margins with the same swell-shear behavior Montana's Pierre shale shows, and shallow bedrock on 20-50 percent of the basin-margin counties. Coal and uranium country (Gillette, Rock Springs) adds mine-related ground considerations. The mountain uplifts (Laramie, Big Horns, Tetons, Wind Rivers) are Precambrian core and Paleozoic rim: steep, rocky, glacially cut, with rock excavation and blasting standard in mountain-valley sites and the state's deepest frost (42-60 inches). Wind erosion shapes everything: shifting sands and blowouts recur in the Red Desert, and snow-fence and drift management appear in utility work. Hydric soils are rare and localized. Slope is minimal in the basins, extreme in the ranges.

Geographic Footprint:Wyoming's counties (Cheyenne, Casper, Gillette, Jackson) are basin-and-uplift country: Ogallala gravel and caliche plus bentonitic shale in the basins, Precambrian rock and glacial valleys in the ranges, and the deepest frost in the lower 48 (42-60 inches). Rock work is the default.

Area-specific FAQ

Do I need to call before digging in Albany County?

Yes. You should contact Wyoming 811 at least 2 working days before any digging so underground lines can be marked.

How deep do footings need to be in Wyoming?

In Wyoming, footings typically need to extend below the frost line, which is around 48 inches here. A local contractor will confirm the code requirement for your site.
