The better, 1 arc second version, of Perito Moreno Glacier is here: http://www.thingiverse.com/thing:591443
This version of Perito Moreno Glacier in Argentina is constructed with SRTM2STL using SRTM data from the Space Shuttle.This is a 3 arc-second file. There is now a 1 arc-second file in my collection that covers a wider area with better resolution. . The photo of my last build is shown with a view from south to north. The glacier shows up well at the bottom (south end). The source code for creating these files is available up on github under the GNU license. Go to github and search for SRTM2STL.
