W. McCurry, NFS, Arap./Roo. NF: USFS began annual area closures in BC 2/1/23. The closures were Eagle, Blob, Bitty Buttress, & Security.
Through 7/31/23, the closures protect a long-established golden eagle nesting territory. Happy Hour, Bihedral & Riviera will remain open as long as visitors stay out of the closed areas.
The Boulder Ranger District with BCC monitors nesting progress & informs climbers about giving eagles space to raise young.
Fed. & state laws prohibit disturbing any nesting bird of prey. Visitors help protect wildlife by respecting closures. Signs are posted at key access pts into the closed areas. Closure info: fs.usda.gov/goto/arp/eagles.
K. Armstrong, Public Affairs Specialist, Nat'l Forest Service: as of 6/8/21: BC areas reopen after unsuccessful nesting.
K. Armstrong, NF Ranger 7/29/20:
Following a 5 mo. closure to protect nesting eagles, the Roosevelt NF has reopened Eagle Rock.
“The BC eagles successfully raised 1 strong & healthy eaglet this year,” wildlife biologist Aurelia DeNasha, USDA FS. “2 chicks hatched initially, only 1 survived to fledge, which isn’t uncommon in birds of prey.”
Visits to the nest did not reveal the exact cause of death of the 2nd chick, but climber cooperation with closures are crucial to the eagles.
“Golden eagle pairs are most susceptible to disturbance when choosing a nest. These closures allow the birds to pick the best site for survival without impact of other factors, such as human presence. Once chosen, nest sites stays closed until the eagles fledge in late July,” said DeNasha.
After the eagles’ site selection was made, unused areas opened in Apr.
The annual nesting closures include popular rock climbing spots at Eagle, Blob, Bitty Buttress, & Security.
Effective through 7/31/20, the closures protect a long-established golden eagle nesting territory. Happy Hour, Bihedral & Riviera remain open as long as visitors stay out of the closed areas.
The Boulder Ranger District partners with BCC & AF to monitor nesting progress and to inform climbers about the importance of giving the eagles space to raise their young.
It is against federal & state law to disturb any nesting bird of prey. Only employees, volunteers, & wildlife professionals under an agreement with the FS enter nesting areas for monitoring purposes. This is for the integrity of nest & the safety of the eagles, those conducting surveys, & the public. Visitors help protect wildlife by respecting all closures & leaving immediately if you should accidentally enter one.

Perennial notice:
Eagle, Blob, Bitty Buttress, & Security will close 2/1 - 7/31 for nesting. Depending on updated information, the closure time can be shortened/lengthened.
Each year, BC raptor nesting area closures are in effect starting 2/1 through 7/31 at Eagle, Security, Blob, & Bitty Buttress. The area is monitored & closures are periodically lifted early (due to no active nest, nest site failure, or early fledging).

Good seeing you on Saturday. Thanks for pointing us in the direction of these new routes. We climbed this one in one long pitch (70 meter rope needed) and it was fantastic. Certainly will get better with more traffic. Would have tried the others in the area had we not lost our sun. The 11d with your draws on it looks stellar too...any idea what the crack to the left (with the obvious pin down low) goes at? Did you put in some anchors for this line?

We did the whole route (12 bolts) with a 60 meter rope but belayed about 10 feet below the first bolt. A 60 meter rope easily makes it from there but as always be careful. Tie a knot in the end of your rope if there is any doubt in your mind. Mar 20, 2008

You can get to the starting ledge for this climb in several ways:
1. Climb Laurel & Hardy Meet Abbott & Costello (9+, bolts) and continue past the two-bolt anchor to a big dead pine tree on a ledge about 70' up.
2. Walk right beneath Laurel & Hardy... for several hundred feet, and find a path cutting back up left to the ledge with the big dead tree.
You can belay by this tree (it is solid enough to be used as an anchor), or scramble up loose ground for 25' to a higher ledge just below the first bolt on the route.
From the higher ledge, it is about 100' to the top anchor. You can lower or rappel with a 60m rope. From the lower ledge with the dead tree, it is about 125' to the top anchor. You would need a 70m rope to lower to here, but be careful if you try this. May 10, 2008

On the behalf of the climbing community, THANKS.
One of the nicest blend of continuity, just enough run out and length.
One of the best 5.10 in Boulder Canyon.
Will do that route again. It's sooooo good!
An alternative to the 60 m being too short to belay from the ground:
Belay the follower from the second belay top anchor, it's comfy enough.
Bonus: A stunning view across the canyon!
Two rappels will bring you back safely on the ground.

Stay left for the crux move, otherwise it's a dead end/way harder. May 12, 2008

Climb on a 70m to return to the starting ledge by the dead tree with no worries. May 16, 2008

The best part was seeing the antique pitons on an old aid line just right of the top of this route. Sep 27, 2009

Otherwise the route was pretty fun. Did it in one pitch with a 70 m. We belayed from the boulder, but I was able to rappel down to the base of upper Animal World. Jun 12, 2014
