Check with users Lunger and Sam Boyce. They did something up there last summer? And we’re at the time unaware of the BB lines as well. They may have a copy. Weird how that guidebook seems to have totally vanished. Had all kinds of random Doorish routes and what not in it.
You might try to track down a copy of Bryan Burdo's old WA-Pass guidebook. He did several routes on that feature (if I'm recognizing it correctly as above the big waterfall east of the pass). I know that a couple other CC users went up there a couple years ago and climbed something.
If anyone is thinking of Colfax with this high pressure. As of 1/13 the Cosley-Houston is not formed, though the Polish Route looks like it may have connected. North and east side of Lincoln look like the future of local Alpinism.
