W. McCurry, NFS, Arap./Roo. NF: USFS began annual area closures in BC 2/1/23. The closures were Eagle, Blob, Bitty Buttress, & Security.

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.
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….

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
Find this climb as the 'tower' of rock protruding from the West Face of Castle Rock, just above Polyester Leisure Suit. This is visible at the right hand edge of the West face route in the attached photograph.
Climb the Big Deal Pinnacle by doing the first pitch of another route, either Polyester Leisure Suit, or P1 of the West Face, or a crack system just left of Polyester, but right of the wide slot next to West Face. I suggest the latter of these options to cover more new territory it is perhaps 5.7 & protects well.
After arriving at one of the two trees, both with anchors, climb up the center face of the pinnacle to access some cracks, or go to the right-hand side, and climb a perfect hands and wide-hands corner for 30' to reach a rising left-hand traverse at a horizontal. (This can be intercepted from the face below as well, apparently). From the left edge of this, move up the edge of the tower and cross back right on another rising traverse on a horizontal--both protect well enough to be safe, but could be exciting. Finish via cracks on the right side of the pinnacle or on the west slab to the summit.
There is no good belay on the summit, but on the shoulder to the climber's right of it, there are cracks, blocks, horns, and a good belay seat.
To descend, finish to the summit on the West Face and do the standard descent, or scramble down to the trees below (climber's left, a 5.6 or 5.7 downclimb) or to the anchors above Bailey's Overhang or Curving Crack (easier?). Then rap off with a single rope.
