Bowie No. 2 Mine (C- 1996 -083) MT- 4 found within some of the drainages, in perched water zones located within the lenticular sandstones of the Mesaverde formation and in the Rollins Sandstone. The Rollins Sandstone is a recognized aquifer in the area. The groundwater associated with the alluvial deposits of the North Fork of the Gunnison River has been developed for domestic and agricultural uses. The localized groundwater resources associated with the alluvial deposits of Hubbard and Terror Creeks are not significantly developed. The groundwater associated with local colluvial deposits is recharged by snowmelt, and the water discharges through local intermittent springs and seeps. Most of this colluvial water is lost due to evaporation. Bedrock groundwater is not abundant in the permit area. The groundwaters of the locally perched bedrock water zones and of the Rollins Sandstone are not significantly developed in the permit and surrounding area, due to relatively poor water quality and low potential quantity yields. The general bedrock groundwater flow direction in the sandstone strata of the Mesaverde formation is from the recharge area near the outcrop of these strata, north toward the lower parts of the basin. Climatological Information - The average minimum temperature in the area is about 36 degrees (Fahrenheit), with the lowest temperature of -28 degrees recorded in Paonia during 1913. The average high temperature in the area is about 64.5 degrees (Fahrenheit), with the highest recorded temperature in Paonia of 100 degrees during 1927 and 1934. The average annual precipitation is 18.50 inches. Soils Information — Generally, the soils within the disturbed areas are shallow to deep, moderately steep to very steep, well drained stony soils that formed in residuum, colluvium, and alluvium derived from sedimentary rock and rock outcrop. The soils in the upper elevations in the northern portion of the permit area are deep, nearly level to steep, well drained loam and stony loam that formed in outwash from igneous rock. The areas within the permit area mapped by BRL exhibit the following soils: the Absarokee (Beenon- Absarokee Association), the Persayo, the Torriorthents, Fughes loam, Cochetopa stony loam, Delson loam, Work loam, Progresso loam, Potts loam, Glenton fine sandy loam, Kech- Rock Outcrop, Saraton -Agua -Fria complex, Haplaquolls, and fluvents. Vegetation Information - Major plant communities within the permit area are: • Juniper Woodland, Mixed Shrub and Disturbed Meadow in the vicinity of the mine haul road, benches and facilities, and Gob Piles #1, #2, and #4. The Juniper Woodland and Mixed Shrub communities exhibit such plant species as Snowberry, Gambel oak and Page 5 of 22
