Slope failure on Hayden Hill's rock dump

At Kinross’s closed Hayden Hill gold mine in northeast California, AMEC’s study of InSAR data focused on a waste rock dump that experienced five notable slope failures during the 1990s. AMEC prepared deformation maps for 24-day periods in the fall of 2001 and fall of 2002 and for an 11-month period stretching from the fall of 2001 to the fall of 2002. The maps show that the waste rock dump was relatively stable during those periods. However, since the availability of high-quality historical satellite data was limited to the fall of 2001 and 2002, new satellite data would be needed to investigate the current stability of the dump.
