Top ranked topographic change polygons

Top ranked topographic change polygons (outlined in yellow): largest fill volume (5.16 x 108 m3), largest mean elevation change (177.3 m), and largest relief change (263.7 m) for a cut. This feature is a gold mining operation near Rodeo Creek in north central Nevada. From left to right, the images are NED shaded relief, SRTM shaded relief with change polygons overlaid (blue = cut; red = fill), and Landsat image. The dates of the source data for the NED and SRTM are shown. This area is about 5.5 km east-west by 9.7 km north-south.
