Fixed Drop, Co 13ers

Got a couple good comments on this(thx john and rick) so thought I'd put it out there for anyone else to check out.

Fixed drop measures how steep a peak is near the summit by averaging the distance from the summit to a point where the elevation drops x feet. Here x is set to 300' as that is the long accepted consensus as to what defines a summit in Colorado. x could be set to anything but the results become severly skewed if x is less than a peaks prominence.

The figures computed below are the average horizontal distance(in feet) to 300' of vertical drop. All directions surrounding a summit are checked in 2 degree increments. In general, the lower the value, the steeper a peak is near its summit.

Actually computing the distances from the DEMs requires crunching a lot of data so I have only run the 14ers-13ers so far.

14ers-13ers(not error checked):
