This article contains visualizations of volcanic landscapes at Mount Shasta, California. The visualizations were created with USGS DEM's and DLG's downloaded from the internet. Although the article is dated, the use of free digital data for educational visualization is as relevant now as ever. Indeed, a GIS-savvy geologist can now create better graphics on a PC than those produced on a Sun SPARC workstation for the 1997 article. The article is also noteworthy because it describes the use of GIS to analyze student mapping.
