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 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.
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.
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
Undercling is a 1-star route that would be 2 stars if it were cleaned up a bit. The mungy start can be skipped completely to make this route a better, cleaner, and safer route. Were it totally cleaned up, the moves and positions could make it 3 stars, but that would take some effort. For now, think of it as a fun route with no crowds but a bit of dirt. You'll have it to yourself.
The initial slab has no protection, some lichen, and some wild rose bushes. It goes 5.6, and is slick when wet. If you fall off of that slab, the injury will probably be serious. This does not detract from the route if you simply don't do it. You can skip the optional and unprotected slabby beginning section and just walk up the hill left of the slab to reach a left-facing, open book. At the back of that lies a set of 2 short roofs. Step up and into the corner on a set of jammed rocks and flakes, then up into a roof. Jam and undercling up and right out of the roof, and turn the corner onto a lower angle set of cracks. Take this up to a slab with a tree in a crack. A belay can be built here with the tree and 2x red Aliens or purple Camalots. You can also sling this long and then head up and right onto a slab placing a black Alien or two in a seam above. There is some PG-13, but it is probably only 5.5. You arrive at the base of a second roof and corner, like the first but bigger and harder. A 1/2 driven blade piton lies next to a green and yellow Alien placement for the belay there.
From the belay, start off on P2, once again heading out to the right under a roof. This second pitch is going to be difficult/awkward for climbers below 5.10, just to get started, so starting pro matters. A grey X4 Xamalot is a great first piece, then the purple Camalot or red Alien again before switching to hand-sized gear. Jam and undercling for about 10' out and right to the flake wedged into the roof, and then head up on this with solid pinches and jams to turn the corner and intercept another crack that will take you to the top on more moderate terrain.
