About this 3D model

The Galapagos sit over a "hot spot" on the earth's crust and have many active volcanos. Here are models of the islands and six volcanos. A very nice introduction to Galapagos geology, which includes descriptions of the individual volcanos, is avaiable at: http://www.geo.cornell.edu/geology/Galapagos.html The models were constructed from NASA's SRTM3 data: http://dds.cr.usgs.gov/srtm/version2_1/ using a program similar to that described in thing:121275.
