Site Type: Rangeland MLRA: 69 - Upper Arkansas Valley Rolling Plains Exposed areas of limestone and bare ground are inherent to this site. Where slopes are gentle, water flow paths should be broken, irregular in appearance or discontinuous with numerous debris dams or vegetative barriers and exhibit slight to no evidence of rills, wind scoured areas or pedestaled plants. As slopes become steep and bare areas increase, expect to find evidence of water flow patterns and pedestaled plants. Sub - surface soil layers, where not affected by bedrock, are non - restrictive to water movement and root penetration. Major soil series correlated to this ecological site include: Penrose Soil series that will be correlated to other MLRA's when outdated soil surveys are updated are: none Other soil series that have been correlated to this site include: Minnequa Parent Material Kind: slope alluvium, residuum Parent Material Origin: limestone Surface Texture: loam Surface Texture Modifier: channery Subsurface Texture Group: loam, clay loam Surface Fragments _< 3" (% Cover): 0 to 35 percent Surface Fragments > 3" ( %Cover): 0 to 15 percent Subsurface Fragments <_ 3" (% Volume): 0 to 35 percent Subsurface Fragments > 3" (% Volume): 0 to 15 percent Rock fragments are generally gravel or channers.
