All surficial <br />slides that can be observed at the property appear to be concen- <br />trated on the steep slope between the elevation about 6,500 and <br />the large flat bench at elevation about 6,640 and higher; this <br />slope is considered to be the least favorable part of the old <br />landslide area for any development. <br />For technical purposes, it is important to know the thick- <br />ness of the surficial slides of this group. It can be reasonably <br />assumed that the slides would be limited only to soils; the <br />thickness of the soil cover indicates maximum possible thickness <br />of these slides. <br />I In the following Table 1, thickness of Che soil cover as it <br />;was found in some of the borings and test pits excavated during <br />~I{our investigations is presented. Data on the ground water depth <br />alas it was encountered are presented as well. <br />1 ~ <br />1 <br />III <br />ao+~ro.o corm~nw nc <br />
