The ground under Cochran County
PredictedMost of the ground under Cochran County is one class on USGS's geologic map: 99.8% of its land is low radon potential, with 0.2% moderate. All of it lies in the area the map calls Southern High Plains and Plateaus, to which USGS gives a radon index of 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Southern High Plains and Plateaus | Paleozoic and Mesozoic sandstone, limestone, shale. | Low | 7 | 99.8% |
