When viewed from Turnpike Road, Potter Mountain is the upper rightmost cliff. The cliff is 400+ tall, and the ice routes are similar to the first pitch of Positive Thinking, but much longer. Like PT, when it's "in", it's easy. Once the cliff gets sun, say goodbye to the ice -- it delaminates and becomes very unstable. Early season is best.
