The first parcel of land was located north of highway 50, on the southern side <br />slope originating at Boswiek Park. The second site was located south of highway 50, on the <br />northern side slope originating at Shin Park, just west of a major drain whose source is also <br />Shin Park to the south. Both sites were of similar landfotm, consisting of eroded stream <br />terraces. <br />Soils on the properties (see attached soils descriptions) were somewhat similar in composition, <br />with a f net textured, less skeletal overburden of soil, underlain by a concentration of gravel <br />and cobbles. Overburden materials in the southern site were of finer texture (fine-loamy) than <br />the site to the north. Irrigation-induced wetlands were present in close proximity of both sites <br />(within 200 to 300 yards), occumng in the bottom of the dissected ten•ace drainageways. Soils <br />upslope of these wetland areas quickly became somewhat excessively to excessively drained. <br />Thickness of the soil overburden material was observed in both areas to range from 0 to greater <br />than b0 inches. Thicknesses of the gravellcobble deposits were noted in both areas to range <br />from a few feet to greater than 50 feet. The land area containing these gravel/cobble deposits <br />seemed to be somewhat smaller and narrower in the site area to the north. Both sites had <br />Mancos shale derived (non-stony) soils in close proximity. Slopes in both locations were <br />dominantly steep or very steep (greater than 15%). This fact, coupled with the thick deposits of <br />graveUcobble in some areas, could make facial extraction of these deposits highly feasible if so <br />The Natural Resources Conservation Service works hand-in-hand with <br />.~ _ ' _--: ... ...... .. ......._.e .._...m~ .o..,,...~~ ,.., ,,.:,,,.P t,.,,t~ _ An' EOUAL OPPORTUNITY Eb1PLOYER <br />
