6 <br /> 7/22/175.1/ A photo of 11/18/ 78 was used for the soil delinea- <br /> tions. From the soils map a mylar was prepared. It is a stripping <br /> isopach showing depth of stripping, classified quality of topsoil <br /> material and limitations. <br /> Field observations and laboratory data were used to prepare inter- <br /> pretations tables 4 and 5. Topsoil quantities were ccuputed from <br /> measurement of the map and soil horizon thickness and quality. <br /> DESCRIPTION OF THE AREA <br /> The area mapped includes the S 2 SW 4, the S; N 2 SW 4 and about 16 <br /> acres in the WZ SW,- SEQ of Section 25, T47N R16W in Montrose <br /> County, Colorado. The total area is approximately 116 acres. A <br /> previously disturbed or stripped area of about 13 acres along the <br /> south border of SE4 SWQ was not typed as a soil map unit. <br /> CLIMATE <br /> The climate is typically continental intermountain with cold win- <br /> ters, moderately hot summers, low rainfall and relatively short <br /> growing seasons. The Colorado Weather Bureau report for Norwood <br /> (nearest longtime station) is shown in Table 1. <br /> Norwood is about 20 miles nearer the mountains at an elevation of <br /> 7020 feet and can be expected to have slightly cooler climate and <br /> higher precipitation than at the Nucla area where elevations of <br /> the field mapped range between 5672 and 5767 feet. With no exact <br /> data, it is anticipated the mean annual temperature (MAT) should <br /> be about 450 F (7.29C) and the mean annual precipitation (MAP) would <br /> be about 12 inches (30.5 centimeters) . The soil temperature zone is <br /> classed as "frigid" (<eC) and the moisture regime as ustic. <br /> Other reports show about 50 inches A-pan evaporation potential <br /> 1/ See clap labelled Job No. 3424 P, Photo 7/22/75, Photo Symbol <br /> BFP.
