  • Description 

    The Blob Rock Area has some of the finest climbing in Boulder Canyon. Located on the sunny north side of the canyon, it's a great place to climb in cooler weather. There is something for all climbers: multi-pitch trad climbs, runout face climbs, and modern sport routes.

    Many of the older routes are a bit runout; they were established at a time when bolting wasn't a popular option for dealing with scary climbing. Most of the modern routes, however, have bolts where necessary to protect difficult moves.

    This area is often closed for raptor nesting from February 1 through July 31. However, in 2006 the climbing ban was lifted early, and the area was reopened to climbing in early March. Signs are posted at the trailhead informing climbers of the current status of the raptor closure.

    The area is composed of several formations: the main rocks are Blob Rock and East Blob; two smaller rocks are Little Blob and Small Package Block.

    Blob Rock is a large and complex formation with many routes. It is the home of multi-pitch trad routes like Where Eagles Dare (10b PG-13) and On Ballet (9), bolts-plus-gear testpieces like Radlands of Infinity (13a) and Bearcat Goes to Hollywood (11d), and modern sport routes like Bolt Cola (10a) and Vasodilator (13a).

    East Blob has some old, runout face climbs like A Hike With Ludwig Dude (10a R), and some well-bolted sport routes like The Young and the Rackless (9), A Hike for Y2K (11d), and The Ticket (12a).

    Little Blob is a small rock below the main face of Blob Rock, and has a few more difficult sport routes like Lost and Found (12a).

    Small Package Block is a small rock up and left of Blob Rock, and has a few short trad and sport routes. Wake 'n Bake (10a, sport) is a lot of fun.

    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.

    An overhanging bolted finger crack way over on the right side of Blob, right of the Blob slab, and up the gully. This is certainly one of the hardest pitches in the canyon and only the big jug in the middle keeps it from solid 5.13c. A stout opening fingercrack (tape!) with no footholds leads to a burly move with really bad footholds. A few more jams lead to a big flake. Relax here because the end is tenuous, awkward, and just a bit hairy on the lead. For you trad purists, doing this route on ge...[more]   Browse More Classics in CO

    CONDITION REPORT 
    The eagles have settled on the nest on Eagle Rock this year and are incubating there. Please be sure to respect that closure.

    Meanwhile, that being the case, the USFS has opened the other area closures now that the other nests are determined not to be used this year. That means as of now, Security Risk, Blob Rock, and Bitty Buttress are open.

    The snow has prevented the USFS from getting to the closure signs so far, but they will be coming down.

    Also - the eagle tag on the first bolt of 'The Young and the Rackless' will be taken off and returned to the BCC for next year. If you are there "first", please either leave it or take it down and return it to the Access Fund or USFS office.

    As of 5/23/09, the raptor closure on Blob Rock has been lifted, and the area is now open to climbing. The eagles did not nest there this year, and the Forest Service lifted the closure early.

    Has anyone climbed the route under the giant roof between Dike Wall and West Butress? The one route that goes under the roof is called "Bad Girls Dream" and according to the new guide book, it's a 10a. It's the only 5.10 in the canyon I have not been able to climb. (Had to downclimb it, not easy in a horizontal roof.) Does anyone know if the 10a rating in the new GB is an error, or have any general info about this line?

    Forest Service Reopens Climbing Areas in Boulder Canyon

    Contact: Maribeth Pecotte, (303) 541-2500

    Boulder, Colo. (April 2, 2010) – The Forest Service has reopened some climbing areas in Boulder Canyon that were closed to protect golden eagles during their nesting season.

    Security Risk and the Blob Rock/Bitty Buttress areas are now open to climbing and other activities. These areas are located along State Highway 119, approximately 1.5 miles east of Boulder Falls.

    These closures help protect a long-established golden eagle nesting territory, including valuable alternate nest sites. Although these areas are being reopened, the Forest Service anticipates reinstating the closures in future years, to allow the eagles to choose their nest site without being disturbed.

    The Eagle Rock area remains closed to climbing and other activities and is expected to remain closed through July 31. Signs will be posted at key access points into the areas remaining closed. Volunteers and Forest Service personnel will continue to monitor the areas.

    Signs will be posted at key access points into the closed areas. Closure information will be available online at local climbing websites and at www.fs.usda.gov/arp (click on Recreation). Closures are effective from Feb. 1 through July 31. Volunteers and Forest Service personnel will monitor the areas, and some areas may be reopened prior to July 31.

    From Bev Baker, Wildlife Biologist:

    The Boulder Ranger District of the Arapaho & Roosevelt National Forests will implement its annual area closures at Security Risk, Eagle Rock, Blob Rock, and Bitty Buttress in Boulder Canyon beginning Feb. 1.

    These areas are located along State Highway 119 approximately 1.5 miles east of Boulder Falls. Happy Hour, Bihedral, and Riviera will remain open, as long as visitors stay out of the closed areas.

    The closures help protect a long-established golden eagle nesting territory, including vital alternate nest sites. Undisturbed access to multiple nest sites is important for birds of prey, especially early in the nesting season, to give them a chance to visit multiple nests during courtship and to select a site for the season, free of human influence.

    BOULDER, Colo. – The Boulder Ranger District of the Arapaho and Roosevelt National Forests implemented its annual area closures at Security Risk, Eagle Rock, Blob Rock, and Bitty Buttress in Boulder Canyon on February 1 to protect golden eagles during their nesting season.

    These areas are located along State Highway 119 approximately 1.5 miles east of Boulder Falls. Happy Hour, Bihedral, and Riviera will remain open, as long as visitors stay out of the closed areas.

(click on Boulder Canyon for more info). Closures are effective from February 1 through July 31.

    The closures help protect a long-established golden eagle nesting territory, including vital alternate nest sites. Undisturbed access to multiple nest sites is important for birds of prey, especially early in the nesting season, to give them a chance to visit multiple nests during courtship and to select a site for the season, free of human influence. “Closures in Boulder Canyon are vitally important to protect one of only a handful of known golden eagle nesting territories in Boulder County. Their specific habitat needs limit what areas they can use for mating and fledging their young,” said Sylvia Clark, Boulder District Ranger.

    Seasonal closure in Boulder Canyon protects nesting birds of prey

    BOULDER, Colo. – To protect nesting golden eagles, the U.S. Forest Service will be implementing annual area closures in Boulder Canyon beginning Feb. 1, 2016. The closures include popular rock climbing spots at Eagle Rock, Blob Rock, Bitty Buttress, and Security Risk in Boulder Canyon. These areas are located along Colorado Highway 119, approximately 1.5 miles east of Boulder Falls.

    Effective through July 31, 2016, the closures protect a long-established golden eagle nesting territory. Happy Hour, Bihedral and Riviera will remain open as long as visitors stay out of the closed areas.

    “These closures allow the birds to choose a nest site without human disturbance. The chosen site remains closed until the eagles fledge in late July, but we typically reopen other parts of the area earlier,” said wildlife biologist Bev Baker.

    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 giving the eagles space to raise their young.

    Federal and 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 information will be available online at local climbing websites and at fs.usda.gov/activity/arp/recre....
