2014 Update: Blob Rock, Bitty Buttress, and all seasonal raptor closure areas on U.S. Forest Service land will be re-opened August 1, 2014 for climbing.
Each year, Boulder Canyon raptor nesting area closures are in effect starting February 1st through July 31st at Eagle Rock, Security Risk, Blob Rock, and Bitty Buttress. However, the area is monitored and closures are periodically lifted early (due to no active nest, nest site failure, or early fledging). This monitoring program is a partnership with the Forest Service Boulder Ranger District, Boulder Climbing Community, and Audubon Society. Check back periodically during times of closure for updates. More info at www.fs.usda.gov/recmain/arp/recreation.
This information is a public crowdsourcing effort between the Access Fund,
and Mountain Project. You should confirm closures, restrictions, and/or related dates.
Dan's Line is another good moderate sport route on the Bihedral.
Start about 20' left of Hold The Line, at a nice sitting boulder by a small pine tree. Climb up and left on a ramp to a stance and clip the first bolt. Make some thin moves past the second bolt, continue up past an easy overhang, and climb up the slab, with some more thin moves, to a a 2-bolt anchor with lowering hooks at 100'.
Lower off this anchor (60m rope is OK), or continue 10' up to a higher anchor. Belay at the higher anchor if you want to do Puff Daddy (10a), which continues above.

8 bolts to a 2-bolt anchor with lowering hooks at 100'. Lower off this anchor with a 60m rope.
Excellent route that felt like a true 5.8. Rarely do I lead a climb without first following someone else up the route. I know, I am a sissy. Anyhow, I led this one without any previous awareness. It was a blast. It held my attention but never scared me. Great route. I highly recommend it.
