<br />3.1.3 Old Landslides <br />Two landslides were mapped earlier by Colorado <br />Geological Survey in the vicinity of the Orchard Valley <br />Mine. Both of them are located about 2,000 feet north <br />of the mine; they were identified east of the distinct, <br />southwest-northeast trending ridge that reaches an <br />elevation of about 8,200 feet at this location. Both <br />landslides are located at the intersection of Sections <br />13, 18, 19 and 24, T13S, R91 and 9241 <br />• <br />Colorado Geological Survey classifies the land- <br />slides as "a landform resulting from the moderate to <br />rapid, downward and outward movement of rock and/or soil <br />where there is a surface of rupture or zone of weakness that <br />separates the landslide from more stable underlying <br />material". Subscripts of 1 and 2 indicate the relative age <br />of the landslides with 1 being the younger one. <br />Both landslides were inspected in the field and <br />on two sets of aerial photographs that were made available <br />to us by C[JI. Based on the field inspection and on the <br />examination of the aerial photographs we concur with the <br />Colorado Geological Survey evaluation that both these <br />features have morphological Features typical for landslides; <br />it is difficult, if not impassible, to estimate with certain- <br />ty whether they are landslides or not. <br /> <br />There are certainly no traces of recent deformations; <br />~~ both landslides would be very old. There are also no reasons <br />~ why the deformations of these landslides should be renewed. <br />The direction of the movement of both these Features is <br />tocaard the east, into an unnamed, deeply incised valley of a <br />- l5 - <br />GEO-MV000 CONSULTING, INC. <br />
