Henrys Fork Area, Utah-Wyoming, Parts of: Daggett and Summit Counties, Utah and Sweetwater and Uinta Counties, Wyoming
The most common soil here is Luhon, on about 11% of the land: a loam, a balanced mix that crumbles in your hand. Poposhia and Blazon come next.
About 94% of the land drains well, and 3% stays wet for long stretches; groundwater comes within two feet of the surface under 2% of it.
USDA rates 65% of the land very limited for a standard septic drain field, and 61% very limited for homes with basements. That means extra cost or special design, not that it can't be done.
Worth knowing: 1% of the land floods occasionally or more, and bedrock lies within 40 inches under 42% of it.

Soil Orders in This Area
The USDA classifies every soil into one of 12 soil orders. Here are the dominant orders found in this survey area.
What This Means
Building & Foundations
About 61% of soils are rated "very limited" for dwellings with basements. Specific challenges include shallow bedrock, steep slopes, poor drainage in some areas, flood-prone areas. A geotechnical assessment is recommended before building.
Septic Systems
About 65% of soils are rated "very limited" for septic absorption fields. Despite good drainage overall, limitations may stem from shallow bedrock, steep slopes, or seasonal conditions. Engineered or alternative systems are frequently required. Always get a professional perc test before purchasing land that needs septic.
Gardening & Agriculture
Well-drained soils on sloped terrain — good for most plants but watch for erosion. Terracing, contour planting, and mulching help retain moisture and topsoil. Drip irrigation is more effective than sprinklers on slopes.
