Description

The Great Northern Slab is where many climb their first time at Index. There are a lot of fun, moderate trad routes, mostly 2-3 pitches in length. When the sun is out, the routes are all in the sun.

If it is too hot, the relatively cool Inner & Side Walls, as well as Lookout Point, also have great moderate (5.9 and below) routes.

Getting There

The trail from the parking lot leads straight to the Great Northern Slab (i.e. don't turn left or right, just go straight).

Does anyone know what the finger crack to the right of the start of the great northern slab is rated/called? Jan 3, 2017
Found a blue rope coiled at the base of Sandy Corner on 12/11/2017. We were the last ones to leave so I picked it up. Let me know if it's yours and we'll figure out how to get it to you. Dec 12, 2017

found some car keys on a small ledge at the top of sickle crack by the blockbuster block on 1/15/18. Probably dropped from somewhere on GNS. Left them on the sign by the porta-potty Jan 16, 2018
