I have to do an oral presentation for my Bio1500 class - Enviormental Science on a topic pertaining to the enviorment. I am going to do a report on Avalanches, but it has to be related to the enviorment. It has to be 3-7 minutes long with 3 references and 3 illustrations. If anyone has any suggestion 's on websites or areas pertaining to Avalanches and the enviroment, your help would be greatly appreciated I'm a newb here.
