The highest elevation was Cascade Canyon in Grand Teton (~7,000 ft and ~2,000 meters I think). Highest mountain however would Algonquin Peak in the Adirondacks (5,114 ft and 1,558 meters). Definitely my favorite mountain, it just looks like a huge slab of land. Lots of scrambling around the rocky peak with a great view of the surrounding mountains.
