The Tetons were the most unique mountains we've seen. They rise almost vertically from a fault line that runs at the base on the mountains, which means that there aren't really any foothills. On the other side of the fault line is Jackson Hole, a valley of sorts ringed by the Tetons on one side and the Gros Ventre Range on the other. It's hard to describe how different the mountains look rising fully formed without the hesitant fits and starts of foothills. It's almost as if you can drive right up to the foot of the mountain, which we came pretty close to doing.
