From K. Armstrong, FS Public Affairs, email@example.com, 970-222-7607: starting 3/20/19, Blob Rock, East Blob Rock, Bitty Buttress, and Security Risk are now open to activities. Eagle Rock remains closed to climbing and other activities through 7/31/19.
The Boulder Ranger District partners with the Boulder Climbing Community and the Access Fund to monitor nesting progress and to inform climbers about the importance of giviSee - fs.usda.gov/recmain/arp/rec….
Eagle Rock, Blob Rock, Bitty Buttress, and Security Risk will close Feb. 1 until July 31 for raptor nesting. Depending on updated information, the closure time can be shortened or lengthened.
Each year, Boulder Canyon raptor nesting area closures are in effect starting February 1st through July 31st at Eagle Rock, Security Risk, Blob Rock, and Bitty Buttress. However, the area is monitored and closures are periodically lifted early (due to no active nest, nest site failure, or early fledging). This monitoring program is a partnership with the Forest Service Boulder Ranger District, Boulder Climbing Community, and Audubon Society. Check back periodically during times of closure for updates.

There are quite a few good routes here, but the most well known is the 2-pitch Bihedral route, which Rossiter so obtusely refers to as "something of a classic".
This area gets good sun and is sometimes sheltered from the wind, which can make it a great place to climb on windless, warmer, winter days.
With a number of new, moderate, mostly bolted routes, this area is a popular place to bring groups and less-experienced climbers. Beware, there are still plenty of loose rocks above.

Cross the road, walk down a bit and find a path that zig-zags up the hill, generally heading right (east). When the trail nears the rock on the right, spot a big pine tree next to the rock. Walk right behind the tree and go left around a rock rib. Climb up the rock, with one short 3rd-class section, to a nice ledge at the bottom of the big dihedral. See Approach to routes on the upper tier of the Bihedral. Follow the approach trail up the hill until it cuts right toward the rock at a flat area. Spot a cairn by a big pine tree close to the rock. Head right, past the tree and around a rock rib. Climb the rock, mostly easy with a short 3rd-class section, up to the upper tier. for the easiest approach.
To return, reverse the above approach, or else walk 50' left (west) on a path just below the Bihedral route, to a 2-bolt rappel anchor. Rap 95' down a gully to the top of the approach trail.
