Katie on what may be the crux of Andromeda Strain....

Access to GFNP (Roadside) REQUIRES a Daily Permit MORE INFO >>>


Great climb in the dry season, but can get a little damp in the wet ones. Start on easy moves to get into a huge corner with a handcrack. Jam and stem up the crack through sustained moves to reach the top. Belay and rap from webbing on trees, and if still present after all of these years, a small stopper placed in a horse's skull.


Go around to the far left and of Roadside Crag. This obvious, huge, right-facing corner is past the long slab in front of you but will appear in the distance and guide you in.


A standard rack with a few extra hand-sized pieces.

In addition to the webbing on the tree, there is (as of 11/2009) a two-bolt anchor with chain and a rap ring at the top of the route.

A stiff 5.9. I personally thought it was a little over-rated.

5-star fun thin hands jamming- mostly #1 camalot sized, although a green and a couple of golds also fit in there.

This route is not .10a, it's .9 at most, especially if you compare it to Rock Wars' upper section.

Oddly enough, Having done Andromeda Strain and Rock Wars including the upper section multiple times each, even on the same weekends, I would have said A.S. is the harder route.
I suppose it may come down to hand size or climbing style.

No move on this route is a 5.10 move. The climbing on this route is a lot more physical than Rock Wars and less physical than Autumn. Classic route, though. Loved it.
