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.
This is a moderately interesting alternative to the Bihedral.
Scramble up to the same ledge where Bihedral starts.
Find a right-facing dihedral system about 100 feet left of the obvious, left-facing dihedral of Bihedral and just right of Edge of Reality.
P1. Angle up & right along this dihedral system. It can be moist with recent rains. Pass a small roof on its right and find a ledge. Belay.
P2. Angle up and right along a small, right-facing dihedral to face climbing to below a crack. Fire up a crack in black-lichen covered rock with slightly tricky jams and top out just left of the finish of Bihedral.

Not a bad route, but a little lichen at the botton and a little choss at the top. As well, it stays wet after a rain for quite some time, as the crack/overlap leaks water.
Can be done in 1 long pitch with a 70m and probably with a 60m at well. I'd take an extra #3 Camalot (3.5" piece) to avoid much swing potential or walking gear too much, and a lot of longer slings and do it in just 1 pitch.
