I'm wondering how accurate google earth's vertical measurements are. On the one hand, it shows Jay Peak's summit at 3,774 feet despite countless measurements and the actual resort's website claiming that it is 3,853 feet high. On the other hand, I was looking at windham on google earth, and things seemed to add up. Windham always seemed to ski a bit short to me as compared to its "1600 foot vertical" or 1550 foot vertical on the main face, and looking at measurements on google earth, the top of the main face is 3,020 feet and the bottom of the mountain is just under 1,700 feet- so it gives a little more than 1,300 feet of vertical. Are both of these google earth measurements accurate, or one, or neither? I don't think that the 3,853 feet claim of Jay Peak would be false as its on so many websites, but google earth does seem to be accurate everywhere else.
