OverviewThe "Thumb" is a large fin shaped formation on the west side of the Sandia Mountains. From the City of Albuquerque the Thumb can be hard to differentiate from the many other rock formations. However, when the Thumb is viewed from north of Albuquerque or Bernalillo areas the Thumb is very prominent. The upper portion of the La Luz trail also offers spectacular views of this amazing rock fin. Many consider the Northwest Ridge of the Thumb to be a classic alpine route. There are also many other trad climbing routes on this fin. There is only one non-technical route to the summit although it is exposed and does require some scrambling.

The Thumb has many technical routes ranging from 5.6 to 5.10. The only non-technical route comes from the saddle on the southeast side. All routes have a great deal of exposure due to the fin shape of this summit.
Southeast Ridge: The only non-technical route on The Thumb. Beginning at the saddle this route requires a 3rd class scramble up the exposed southeast ridge.
Northwest Ridge: Considered a classic line and one of the best in the Sandias. This 5.6 route is six pitches with a few hundred feet of 3rd and 4th class scrambling at the top. This route has lots of exposure.
Other technical routes There are numerous other technical routes that take a more direct line than the northwest ridge route. There are many rock climbing books available that contain the details of these other routes.
