Access Issue: Warning for the Great Northern Slab and Sonic Slab areas on the west (left) end
Details
In late Nov 2023, there was a significant rockfall encompassing the GNS, Sonic Slab, and Roger's Corner areas. There is still a ton of rock on the upper section that will very likely come down in the near future. This rock includes small and very large boulders. Please respect closures and avoid this region for the foreseeable future. For more information or updates please refer to the Climb Index! facebook page.
Access Issue: Warning: area closed off from late June, 2022 due to recent rockfall.

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).
[Hide Comment] 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.

[Hide Comment] 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
