Additional exploration and testing of samples are needed to estimate mlnable tonnage. Soils There are two soil associations within this WSA. The majority of the unit belongs to the Rockland Rock outcrop association. The very western edge of the unit around Cottonwood and Middle Cottonwood Creek lies in the Dominson-San Isabel Association. Refer to Appendix B for more detail. Water This unit produces very little water. Several ephemeral drainages flow through the area, then empty into the Arkansas River. The headwaters are In the San Isabel National Forest, bordering the unit on the east. High intensity thunderstorms occasionally cause flooding in these drainages. The average annual sediment yield is low (less than acre-foot per square mile) due in part to the large amount of rock outcrop in this area. Ground water is very scarce. It is possible that some of the alluvial deposits in the drainage bottoms would yield sufficient water for domestic or stock watering purposes. Range This WSA contains portions of two grazing allotments with approximately 65 animal unit months (AUMs). The area is considered marginal for livestock forage production but is ecologically stable. Primary range forage is mostly blue grama, Arizona fescue, and mountain 'muhly grasses. Allotment management plans.
