Moderate
Crook County, WY: USDA's soil survey rates 36.3% of the county "Moderate" for shrink-swell potential (4.92% linear extensibility). That's a middle reading: not the sharp swings that crack a foundation outright, but enough that grading and drainage are worth getting right.
What Crook County's reading doesn't cover
Two lots a mile apart in Crook County can carry different soil, even though they share one countywide reading. A local geotechnical report, typically $1,000-$5,000 (around $2,700 typical), is the only way to know what one lot in Crook County will actually do.
