• and 8, Soil Profile Descriptions and Soil Mapping IInit Descriptions, <br />respectively. The mapping of these areas was done by the IISDA Soil <br />Conservation Service with an Order 3 sampling intensity. <br />Mottling of the soils in the root zone is a characeriatic of <br />subirrigation which is identified in standard SCS soil descriptions. <br />The Yampa (12A) and IInnamed 30 (30A) soil types are described as <br />being mottled from the surface horizon down to the water table. All <br />three of the soils are described as having been formed in mined <br />alluvium. <br />From these descriptions of mottling in the root zone of Yampa <br />(129) and IInnamed 30 (30A), it can be concluded that at certain <br />times of the year soil moisture is high enough to saturate the root <br />zone. <br />Vegetation <br />The drainages of Foidel, Middle, and Fish Creeks were surveyed <br />for vegetation Cype, density, and diversity. All three areas were <br />similar in vegetation patterns. A complete description of <br />vegetation patterns is provided under 2.04.10, and is summarized <br />below. <br />Grasses and sedges give the site its characteristic appearance. <br />Forba constitute 7.Ox of the plant community. Nebraska sedge and <br />• other unidentified species in the genera Caren contribute 82.2X of <br />the community while bluegrass, meadow foatail, smooth brume, <br />2.06-18 <br />
