As its name indicates, the main draw here is the long, overhanging traverse on the boulder's east side. Climb from a sit down start just about anywhere for some V0 fun. There is also a pretty sweet little dyno from a pair of slopers to the lip on the south side of the east overhang.
Again, mostly flat, sandy landings, but watch out for the bushes.
This is just northwest of Mongoose Block. If you can't see it, keep looking. The Traverse Boulder is a massive boulder, but it is rather short and often obscured by brush. Bushwhack around a little, and you'll find it.
Mountain Project's determination of some of the classic, most popular, highest rated routes for Traverse Boulder (aka Trail Blob Boulder):
There's a new sit start line I just put up on the south face of Traverse Boulder (can't miss it). I dug it out and cleaned it pretty good, it still could use some more at the top, but good. I named it Arch of Doom (you will see why) Go's at V4. Have fun! It's surprisingly good and direct!
I'm working an extended version of the traverse. Starting from a couple of slopers just around the northeast corner of the traverse, working my way south across the east face (just above the heinous slopers), dropping down and heading around the southeast corner to a crimpy traverse of the south face and ending at the huge ledge. Will someone else please try this and rate it for me?
I completed the extended traverse, though I did use a few of the sharp holds on the lip above the regular traverse. It's still a really powerful endurance problem, but I'm not sure if it's a V7 (having not done one before).
