Casey starts up the 5.8 entry to the GNS


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).

Unfortunately, all of the pitches are very short (some less than 30 feet). I've left the rating on this route at 5.8+, but if you're new to Index climbing you are in for a big surprise. This route would easily be rated 5.9+ or 5.10A in Leavenworth.The approach is a piece of cake. Cross the tracks and follow th...[more]   Browse More Classics in WA
