Replying to Ski Resort Map

i know some people on the site might bash me for creating another "need help for my school project" thread but i just searched my ass off at google and couldn´t find anything so i´ll just give it a try here..
i´m working on a report about skiing in the rocky mountains in general, about 20 pages long.. i´d like to add a map of the rockies with all ski resorts marked in it, just to point out the high figure of ski resorts.

thanks ahead for helping me out!
