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.

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
Blob Rock is a huge, south-facing rock with many routes, ranging from one-pitch sport to four-pitch trad. Most newer routes are well-protected, but some of the old classics are a bit runout.
Due to its complexity, Block Rock is broken into several subareas. From left to right:
West Buttress - is on the far left side of the rock. It is home to trad routes Divine Wind (11b) and Night Stalker (9), and several short sport routes.
Dike Wall - is the smooth wall left of the Central Chimney. It has sport route Wild Cat (11a), a runout bolted route Bearcat Goes to Hollywood (11d), and the crack climb Wounded Knee (11b).
Central Chimney - is the prominent, slanting chimney that runs up the entire rock. The Radlands of Infinity (13a) and Tempest (10c) are the attractions here.
Main Wall - is the area right of the Central Chimney. There are lots of good climbs here, including October Surprise (10b), On Ballet (8+), Cold Fusion (10c), Bolt Cola (10a), and Where Eagles Dare (10b).
Right Gully - is the gully running up the right side of Blob Rock. It is the home of hard sport routes Jolt Cola (12a) and Vasodilator (13a).
Upper East Face - is above a giant chockstone in the Right Gully. It is home to trad route Conan (11d) and sport route Erki Nool (11d).

Getting There
Park in a small pullout on the right, just past Cob Rock. This is about 6.7 miles up the canyon.
A trail begins from the right side of the pullout. Follow it as it zig-zags up the hill. It will take you to the base of the Main Wall of Blob Rock in about 10 or 15 minutes.
Per L Kap: take the left fork (easy to miss) at the raptor closure sign, which is turned around backwards when there is no raptor closure.
