Me on the FA (?), mid crux. Jimi Thornburg photo.


Great location, cool moves and good rock. This quasi unique route was named after an article in the LA Weekly about how Gin was making a comeback... like it ever went away!

The crux involves a fairly giant move out of steep laybacks to gain the featured rock above. Standard bolt clipping on perfect gold rock will lead you to the summit. At various times there are runners and extendo clips on some of the bolts. Probably height dependent in spots, and certainly span dependent at the crux.


This route starts at the blunt arete directly right of Tumbling Rainbow. If you are standing at the start of Tumbling Rainbow, and extend your right arm, you might actually be fingering the opening holds.


Bolts (6?), with a bolt anchor on the top. 60m cord will get you down.

I tried this years ago and it seems to me that some of those handholds at the crux have shuffled off their mortal coil. Is this true? Aside from that, both this and Tic-Tic Boom (with which Tonic Boom shares an ending) are phenomenal routes.

The beauty of it is there are really no holds. On the pre-FA, there was even talk by some of the route needing a bolt on hold!!!! The giant span between the layback and the overlap is all there really is to work with. I'm a +5 ape index, at 5'10", and needed every bit of the reach.
