The ground under Holmes County
PredictedUSGS's geologic map puts all of Holmes County's mapped land in one class: low radon potential. The map puts 44.0% of Holmes County in the area it calls North Central Hills/Flatwoods and 30.5% in Mississippi Alluvial Plain, with one smaller area beside them. USGS gives both a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| North Central Hills/Flatwoods | Tertiary nonmarine to deltaic sediments ranging from sand to clay. | Low | 8 | 44.0% |
| Mississippi Alluvial Plain | Alluvial sand, silt, gravel, and clay. | Low | 8 | 30.5% |
| Loess Hills | Loess. | Low | 7 | 25.4% |
