I used a mask of the 15 mile buffers in the Viewshed Environment settings to cut the processing time and output down to what I wanted.&nbsp; Then I extracted just the "visible" (1) pixels and created a polygon from it.&nbsp; This created tons of little pieces per site, so I had to use dissolve to get them all into one polygon.
