This route is technically on the east side of Bumblie Rock, but in the Transformer Corridor. Starts in the chimney and is long with a chimney start that can be a bit tricky. Lots of dishes and rounded knobs, and bolts, lots of bolts. 2 ropes for the rap.


All Bolts and chain anchors. Lts and lots of bolts!

Really fun route. Has a tricky start for which you might want a bit of pro. The start is definitely the crux! From then on, solid friction cruising. Jun 4, 2008

Bolts are pretty spaced out, you can barely lower off with a 70m rope. Jun 9, 2008
This is a beautiful friction route. Getting off the ground is the crux. The first bolt is extremely high, but the climbing in the chimney is easy. We did two raps with a 60M rope. There's some webbing/rap ring 2/3 of the way up the climb around a hole in the rock near the gully. Sep 7, 2009

Just climbed this route and the webbing and rap rings mentioned are now gone. We used a 70m rope and had about 1-2 meters left after being lowered. Fun route with a bouldery, finger long start. Jul 7, 2010

Great rock with scenic views at the top. The start is the most challenging part. Lowered off with no problems using a 70m rope. Jun 25, 2012
Agreed that the first few moves are the hardest, after that its solid 5.9 climbing. A few exposed friction moves up top. Oct 14, 2013

For what it is worth, I did not think the beginning of the climb was the crux or particularly difficult. The first bolt is high though. However, I thought several sections of face climbing were more difficult and quite runout. The bolts are 20 feet apart in spots and the rock is a bit sandy. I thought it was hard and intimidating for a 5.9, at least compared to the other 9s and 10s I did that week. Sep 26, 2014

If you extend your rappel device a 70m works fine. Jun 26, 2016
