Effective 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 partners with the BCC to monitor nesting progress & to inform climbers about the importance of giving the eagles space to raise young.

Federal & state laws prohibit disturbing any nesting bird of prey. Visitors can help protect wildlife by respecting all closures. Signs will be posted at key access points 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 month closure to protect nesting eagles, the Roosevelt NF has reopened Eagle Rock climbing area in BC.

“The BC eagles successfully raised 1 strong and healthy eaglet this year,” said wildlife biologist Aurelia DeNasha, USDA FS. “2 chicks hatched initially, but unfortunately 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 cooperation by climbers with the closures are crucial to the eagles’ success each season.

“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, the nest site stays closed until the eagles fledge in late July,” said DeNasha.

After the eagles’ site selection was made unused areas reopened in April.

The annual nesting closures include popular rock climbing spots at Eagle Rock, Blob Rock, Bitty Buttress & Security Risk in BC.

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 and state law to disturb any nesting bird of prey. Only employees, volunteers, and wildlife professionals under an agreement with the Forest Service enter nesting areas for monitoring purposes. This is for the integrity of nest and the safety of the eagles, those conducting surveys, and the public. Visitors can help protect wildlife by respecting all closures and leaving immediately if you should accidentally enter one.

Perennial notice:
Eagle Rock, Blob Rock, Bitty Buttress, & Security Risk 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 Rock, Security Risk, Blob Rock, & 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.

From: Tammy J. Williams, MS: (7/31/19) The USFS reopened the Eagle Rock. The FS temporarily closes the climbing area near Boulder Falls every year in February, allowing golden eagles to select a nesting site. The nest site then remains closed until the end of July when the chicks typically fledge.

The Boulder Ranger District partners with the Boulder Climbing Community & the Access Fund to monitor nesting progress & to inform climbers about the importance of giving the eagles space to raise their young.

Closure information can be found online at local climbing websites and at fs.usda.gov/goto/arp/eagles.

7/19/17: from Bev Baker:

One bird successfully fledged this year. Egg laying & therefore fledging were a bit earlier than some other years, so we have reopened the area earlier than 7/31. Signs were removed yesterday.

BOULDER, Colo. To protect nesting golden eagles, the U.S. Forest Service will be implementing annual area closures in Boulder Canyon beginning 2/1/17.
