Carbon County, UT Roof Snow Load - Case Study Area
What "Case Study" means for Carbon County
Carbon County sits in the mountain-west terrain where ASCE 7-22 §7.2 itself declines to give a contour figure - elevation changes too fast over short distances there for one number per county to mean anything. The code requires a site-specific study for a building here, not a look-up.
Carbon County, FIPS 49007, is home to 20,613 people - one of 386 US counties ASCE 7 itself routes around a map figure for.

How much it actually snows in Carbon County
Most winters bring Carbon County roughly 11 in. of snow - NOAA's normal at CASTLEDALE HUNTER UP&L, UT US, 41.7 mi off. Worth noting: the nearest station reporting snowfall normals sits 41.7 mi from Carbon County's center, so treat this as a regional figure rather than an exact one. (fresh vs. packed vs. ice explains why.)
Read this before you rely on it
Carbon County's number above is ASCE 7-22's default case, not a custom calculation: ordinary residential occupancy, heated, sited on ground that's neither fully sheltered nor fully exposed. Any one of those changing - pitch, exposure, heating, occupancy - moves the real figure.
Nothing here substitutes for an address-level number. Get one free, in about a minute, from the ASCE 7 Hazard Tool using your own coordinates rather than Carbon County's county-wide figure. Details: the calculation guide.
