Tom’s Thumb is a very prominent pillar resting against the South Summit Wall that attracts the eye of every climber visiting the amazing Lone Peak Cirque. The rock on this obelisk is of excellent quality and provides very secure gear placements. It is no surprise that Center Thumb is one of the best routes in the Cirque. A true classic!

Center Thumb links weaknesses and ascends crack systems shooting straight up the middle of the pillar formation. This is one of the best 5.9 climbs in the Cirque and should not be missed if you visit the area. The route is not very sustained but very varied and continuous, with most pitches checking in at 5.7 or 5.8. The crux is a short but steep and exposed hand crack that drops you on top of Tom's Thumb, and it's spectacular. Every pitch on this route is fun and varied, with mostly hand and finger cracks, and also features lots of cool knobs and patina. As with all the routes in the Cirque, the Summit is incredible and offers fantastic views of the Wasatch Range.

Lone Peak Cirque sits high above a pristine alpine meadow, where melting snowfields provide the only source of fresh water, so plan accordingly. The approach is fairly long and strenuous, and most parties will want to spend at least one night to camp once up there. Beware of fast moving thunderstorms.
