Access Issue: Seasonal Closures 2024 - Bitty Buttress, Blob (Eagle Rock & Security Risk now open!)
Details
FS (3/27/24): Eagle Rock & Security Risk are now open!
2/1/24: W. McCurry: to protect nesting golden eagles, U.S. FS annual area closures in Boulder Canyon beginning 2/1/24 - Blob Rock, Bitty Buttress, Eagle Rock, Security Risk.
USFS lifted closures 7/26/23.
From W. McCurry: 2/10/23 Blob, Bitty Buttress, & Security Risk opened. Eagle Rock stayed closed - info: fs.usda.gov/detail/arp/news….
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 the 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.
For the most current closure information, check signs in the areas, call the Boulder Ranger District office @ 303-541-2500, or visit local climbing websites or fs.usda.gov/recmain/arp/rec….
As of 4/21/20, Blob Rock, East Blob Rock, Bitty Buttress, & Security Risk are open. Eagle Rock stays closed until 7/31/2020 confirmed with Matt Henry, Rec Prog Mgr, FS.
From K. Armstrong, FS Pub Aff, katherine.armstrong@usda.gov, 970-222-7607: 3/20/19, Blob, East Blob, Bitty Buttress, & Security are open. Eagle stays closed to climbing & other activities through 7/31/19.
The Boulder Ranger District partners with BCC & AF to monitor nesting progress & to inform climbers.
See - fs.usda.gov/recmain/arp/rec….
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). This monitoring program is a partnership with the FS Boulder Ranger District, BCC, & Audubon Society. Check back periodically during times of closure for updates.

Description
This secluded, seldom-done climb is worth seeking out.
The route climbs a left-arching thin crack and ramp with a pine tree at the top, starting in an alcove left of the Three Dihedrals; see boulderclimbs.com/climbing/…
Approach: There are two ways to get to the climb:
1. From the creek, climb up the talus field above the Tyrolean traverse to the branch trail to Tarot Wall. Go 30' left on the branch trail, then head right and up on a faint trail. Continue up until you can cut left across some rocks below the three dihedrals to a wooded gully. Go up the gully to an alcove at the start of the climb.
2. From the Dominator-Clipboard area, head downhill past the big dead tree. At your first opportunity, cut right across some rocks below the three dihedrals to a wooded gully. Go up the gully to an alcove at the start of the climb.
The route: stem the corner at the back of the alcove to a stance just right of the crack. Step left and climb the crack and ramp. Belay from the pine tree at the top.
Descent: rappel 40' from slings and rings on the tree.
I used gear from a blue to an orange Alien and a #3 Ball Nut for pro. Double green and yellow Aliens are useful.
Sustained, interesting climbing; would get two stars if it were longer.
