  6. Mountain Glacier • During Nevada’s last ice age, the mountains would have looked similar to this mountain glacier. http://www.bing.com/images/search?q=continental+glacier&id=1A2EF6E62C15862560E0A7DD375141B8A4AD3B46&FORM=IQFRBA#view=detail&id=2B9718333BE1272A956810B7A0C6B883AEE2A4E1&selectedIndex=7

  13. Mt Wheeler, Nevada • “Great Basin National Park is home to the only glacier in Nevada, and one of the southernmost glaciers in the United States. The Wheeler Peak Glacier sits at the base of Wheeler Peak, in a protected cirque around 11,500 feet in elevation. The glacier measures 300 feet long and 400 feet wide. Exact depth is unknown.” http://www.nps.gov/grba/naturescience/glaciers.htm

  14. Deflation • DEFLATION, in geology, EROSION by WIND of loose material from flat areas of dry, uncemented sediments such as those occurring in deserts, dry lake beds, floodplains, and glacial outwash plains. • www.brittanica.com http://www.geokem.com/images/scans/Cottrells-Blowout.jpg http://www.indiana.edu/~g103/theinteractiveearth/10%20-Deserts%20and%20Glaciers/deflatpic.jpg
