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 quality granite crag which faces west, southwest and is very much partitioned off by its neighboring cliffs below. There are approximately 3 established routes, one with a classic, right-leaning dihedral, a few top-ropes have been done on the left side of the wall. On its summit you will find a unique quality granite block with great boulder problems.
Drive up Boulder Canyon, past Boulder Falls for about 8 miles and park in the large pull-out on the right. On the left you will see the Mindshift Cliff and on the right you will see the Lion's Den. Hike the short, but steep gully, staying mostly on its right side between the two road side cliffs. The Law of Physics Crag sit above the Lion's Den and is obscured by it and large trees.
On the way to Bachar's Block, I found this problem -
Take the gully to the left of "Law of Physics" Crag until you are parallel with "Mind Shaft Cliff". Make a right, between another abandoned mine shaft and a large pile of rocks, and walk about 200ft. It is directly on the trial. If you see Bachar Block, you have gone too far.
