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.

Definitely no camping or overnight parking in Boulder Canyon, and with recent area fires started by transients, I would expect serious scrutiny for any camping on National Forest land in the vicinity as well. Apr 19, 2017

From Bev Baker, USFS Biologist: Boulder, Colo. (March 9, 2017) – This Friday, March 10 the U.S. Forest Service will reopen Blob Rock, Bitty Buttress, and Security Risk climbing areas in Boulder Canyon. The Eagle Rock area remains closed to climbing and other activities and is expected to remain closed through July 31, 2017.

These areas were closed February 1 to protect golden eagles during their nesting season. The areas, approximately 1.5 miles east of Boulder Falls, are located along State Highway 119. Forest Service officials anticipate reinstating these closures annually on February 1 in the future to allow the birds to choose nest sites without being disturbed.

It is against federal and state law to disturb any nesting bird of prey. Visitors can help protect wildlife by respecting all closures and 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 at 303-541-2500, or visit local climbing websites or fs.usda.gov/recmain/arp/rec… (click on Boulder Canyon for more info). Mar 12, 2017

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/re…. Jan 31, 2016

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.

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/recmain/arp/rec… (click on Boulder Canyon for more info). Closures are effective from February 1 through July 31. Volunteers and Forest Service personnel will monitor the areas, and some areas may be reopened prior to July 31. It is against Federal and State law to disturb any nesting bird of prey.

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. Contact Boulder Ranger District at 303-541-2500 for more information. Feb 3, 2014

Bad Girls Dream, 12d in Rolofson's guide. Nov 6, 2009
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? Oct 21, 2009
