Wymore soil series
Wymore soils cover 1,204,907 mapped acres, mostly in Nebraska and Kansas. USDA rates shrink-swell a limit for houses without basements on 100% of that land, and a shallow water table a limit for basements on 100%.
It is the leading soil series by area in 8 of the counties and cities on this site, including Gage County, NE; Marshall County, KS; Brown County, KS.
