Information on Soil Resources can be found in the permit application in Section 2.04.9. Additional <br />information can be found in Exhibit D, which is a map of the soils on and adjacent to the permit area. <br />A soil survey was conducted on the Blue Ribbon Mine permit area and adjacent areas on July 29, <br />1981. The field analysis and laboratory data were used to determine soil suitability as a plant growth <br />medium and soil requirements for successful revegetation. <br />Five map units, consisting of three soil series and three miscellaneous types, were identified. The <br />units included Absarokee, Pollard-Torriorthents, Work Clay loams, Disturbed land, and Fluvents. <br />Disturbed land was considered the areas disturbed by mine development. <br />The influence of topography is readily apparent in the development of the soils at the Blue Ribbon <br />Mine. On the east-facing slope to the west of the mine, the soils aze generally deep (more than 60 <br />inches) and have clayey subsoils. On the west-facing ridge, those slopes with a more southerly <br />exposure are generally shallow (less than 20 inches) to moderately deep (20 to 40 inches) and are <br />clayey throughout. On the more northerly exposures on the west-facing ridge, the soils are <br />moderately deep to deep, and have clayey subsoils. <br />Vegetation -Rule 2.04.10 <br />Specific information regazding collection and analysis of vegetation can be found in Section 2.04.10. <br />Additional information can be found in Exhibit E. <br />Vegetation communities on the Blue Ribbon Mine permit area were surveyed on July 29, 1981. Five <br />communities were identified and their distributions are shown in Exhibit E. The communities are <br />oak shrub (west aspect and east aspect), mountain mahogany, ripazian, and disturbed areas. These <br />communities are still evident with the exception of the disturbed area, since the mine is now mostly <br />reclaimed. <br />The west aspect, oak shrub community can be found along the northeastern edge of the permit area. <br />The dominant ovetstory species is Gambel oak. Grasses were found only in openings in the oak <br />shrub, and were practically nonexistent under the dense stands. The slope of this area varies From <br />l5 to 50 percent, with a west aspect. At the time of the survey it was noted that this community had <br />been extensively grazed, with Indian Ricegrass showing the heaviest signs of use. <br />The Mountain mahogany and Oak shrub community can be found along the southeastern side of the <br />permit area. The slope vanes from 40 to 70 percent, and has a southwest aspect. Due to the aspect, <br />the vegetation on the southwest-facing slope is not as dense as the oak shtub community with the <br />west aspect. <br />The riparian community is found along Hubbard Creek. The community varies in width from 20 to <br />120 feet. The dominant overstory species is willow. Boxelder and Alder are also found in the <br />overstory. The understory dominants are Canada thistle; Redtop, Kentucky bluegrass, and sedges. <br />Due [o the mining operation, much of the riparian community had been disturbed down to the edge <br />a• <br />
