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.
"Climb a thin crack near the center of the wall to a bulge and then up to a tree." - D'Antonio, Boulder Canyon Rock Climbs
Additional details: start at a lichen covered crack system just right of an obvious, left-facing dihedral. This is actually more toward the upper end of the wall. Locating the lone bolt for Racing the Sun, the route just uphill will help further. Head straight up to a small roof, then slightly left using a horizontal and then up to a shelf using the nice but short, left-leaning corner. From the center of the shelf, not the crack to left which is much harder, climb up highly featured rock with liebacking and smearing to the jugs on lip of upper ledge. Work left along the lip with better feet and a dirty flake to reach the tree.
The climbing is nice and varied. Expect a bit of spice due to lichen coverage, and a fall from the upper section would land you on the shelf.
This is on Cob Rock's East Wall. To locate the East Wall, walk up and left along the base of the formation, eventually coming around a corner to reveal the small wall. See the description for additional details.
Micro-cams, small stoppers for the start, and a gray c4 at the base of the roof to protect the moves onto the midway shelf. I was not able to find worthwhile protection for the climbing above the shelf, but an ideal stopper and micro cam can be placed while standing on the shelf. The tree is solid.
