Soils are generally shallow and coarse-grained. Derivation is
from the underlying sandstones and shales. Bedrock exposures are
common and scattered throughout the area. The valley bottoms are
characterized by alluvial and colluvial deposits which are also
coarse-grained and deeper than soils of the mountain slopes.
Vegetation varies from riparian and blue grama complexes in the
valley bottoms to pinyon-juniper, oak brush, and pine cover on the
side slopes. Vegetation cover ranges from 100% in the valley bottoms
to near 0% on the steeper side slope rock outcrop areas.
1.2 Sampling Station Descriptions
A monthly sampling program has been conducted since February 1984
to assess the affect of mining operations on surface and ground water
quality and quantity. Tables 1 and 2 are a summary of the current
water monitoring program. This program has undergone several
revisions over the last six years. These revisions have resulted from
data review by the Division and WFC. Sampling emphasis has been
placed on some of the stations because of increased mine operations
on the surface (as discussed in the Annual Report of 1984) . Following
are descriptions of the current sampling locations. Station
locations are shown on Figure 1.
PRS-1 Located on the Middle Fork of the Purgatoire River above
the surface facilities of the New Elk Mine. This station
was selected to assess stream quality and flow above
mining activities.
PRS-2 Located on the Purgatoire River below the New Elk and
above the Golden Eagle surface facilities. This station
was selected to assess stream quality and flow relating
to potential effects of the New Elk Mine and establish
baseline data above the Golden Eagle Mine.
