Google is always adding neat bits of information to its Maps database, and today its adding select ski resorts to that list. Users viewing certain ski slopes around the U.S. and Canada will now see ski runs, gondola routes and more right from the regular Google Maps interface. Different runs and routes show up as soon as you zoom in to a certain point, and show as both blue and green lines labeled with the route name. Gondola routes show as red dashed lines as well.
The list of mapped ski slopes is pretty limited right now unfortunately, with 38 different resorts listed in the post. But just like when Google started to map the insides of buildings, parks and other (relatively) small areas, these features will take some time to populate. We wouldn't expect that list to stay small for very long.
