For my own amusement I spent a few evenings drawing the Steamboat trail map on Google Earth. Have a look at the attached kmz file in Google Earth and let me know what you think. There will undoubtedly be some errors, so please let me know if you spot any and I'll fix them. For some runs (e.g. First Chance, Last Chance, Big Meadow, and part of Rendezvous Way) I just couldn't match the trail map to the features on the ground, so I had to guess. Also, I couldn't figure out the route of the Christie Peak Express (perhaps because it wasn't build/complete when the picture was taken) - did they re-use the old Christie III lift towers? I've assumed so and drawn it that way.
It's a shame that Google Earth don't have a winter picture of the Steamboat area because that would look great. (They do have one of Whister and it looks awesome - you see skiers and their rooster tails!)
Hope you like it and find it useful.
