Porter is a long ridge stretching from near Keene Valley almost to Cascade Pass. There are many humps and bumps along Porter, including the summit, which just manages to top out at a little over 4000 feet. There are many superb open areas and viewpoints along the ridge, and the summit itself has a nice open area. A premier way to do this peak is to start in Keene Valley, at the southwest corner of the Marcy airfield, and traverse over the entire ridge, and end at the Cascade Mountain trailhead near Cascade Pass on Rte 73 (and when doing this you might as well do Cascade Mountain as well!).
