' Exhibit B - Site Description - Soils Information
' The proposed affected area has been previously disturbed by historic
' mining activity and is situated at an elevation of about 9,600 feet on a
northwesterly-facing slope. The affected area itself has been denuded of
' soil and covered for the most part with old mine waste rock. Very small
pockets of soil may be found among the disturbance but are insignificant in
t extent. To the east, south and west, outside the affected area, native
' soil is present.
The area has been described and mapped by the USDA Soil Conservation
' Service (SCS). The Figure Bl map included herein provides a general
delineation of the soils present in the subject area. The Figure B1 map is
' based on an adaptation of the available SCS data and additional field
observations conducted in August, 1987. The soils present are
'
representative of the Schofield-Peeler complex, the Matcher stony sandy
loam and a small area of histosols adjacent to Gold Creek.
The Schofield-Peeler complex includes soils of both representative
' soil series but have not been distinguished for the purposes of delineating
mapping units. Both the Schofield and Peeler series are fine-loamy, mixed
