I've created a Google Earth Map of many Colorado Passes. So far, I have 146 different passes mapped. I've divided them into two types: 1) Paved Roads (62 passes), and 2) Unpaved Roads (84 passes). Instructions: 1) Get and Install Google Earth. (Not Google Maps). 2) Download Colorado Passes. (Should automatically open inside Google Earth). After you've successfully opened the "Colorado Passes" within "Google Earth", try this (within Google Earth): 1) In the map area, click on any pass, so you see the white bubble. In the bubble, click on "To here". 2) Again in the map area, click on another pass so you see the white bubble. In the bubble, click on "From here". 3) Look at the cool turn-by-turn map. 4) In the left pane, under the turn-by-turn directions, click the little "Play Tour" button (looks like a small right-arrow). Happy Google Earth-ing... .
