2014 Update: Blob Rock, Bitty Buttress, and all seasonal raptor closure areas on U.S. Forest Service land will be re-opened August 1, 2014 for climbing.
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. More info at www.fs.usda.gov/recmain/arp/recreation.
This information is a public crowdsourcing effort between the Access Fund,
and Mountain Project. You should confirm closures, restrictions, and/or related dates.
Evolution Revolution climbs up to and over the imposing roof to the left of 'Global Gorilla.' A couple of 5.11 slab cruxes down low will keep your mind occupied and will keep you from constantly staring at the roof above. A no hands rest half way up allows a full recovery before heading up the final slab to the base of the roof. It's steeper than it looks! After a few strenuous moves and a tough clip, pull over the roof and you're home-free!
This route is excellent!! Stays dry in a downpour. Long runner on the bolt before the roof to reduce drag. My book suggests gear, but with 9 bolts, you dont need it. Perfect stone. A good start is with the first 2 clips of Global Gorilla and straight up to the second bolt of ER.
ER felt really burly in the roof. Stacking up under the roof leaves you with two, perhaps three at the most, hand transitions leading to the corner of the roof where terrific jug awaits. It seemed as though the hardest thing was to stabilize the barn-door when standing up under the roof. Can't ask for better pro - gives you a top rope through most of the crux. The run up to the anchors after turning the roof was on jugs. The opening 5.11 was more awkward than it looked to be from the ground; just thrutch through the corner. Two stars probably fits.
ER is a subvertical slab that climbs up to a no hands rest that is followed by a short, burly sequence to the corner of a roof, after which it calms down completely. One and one half stars is probably reasonable given the proximity of GG and Hands. However, I wouldn't call it a great route; I'd call it a good route.
From the top of ER, there is a dihedral that goes up and left (5.7-5.8?) that gets you to the top of H of D. Bring a few pieces (large nuts, TCUs). From here, you can either TR Hands or lead the upper 10a headwall (5 bolts). Fun section of face with black knobs and slopey edges and dishes. Kinda dirty still... If you really want, you can set a TR on Animal Instinct and Sun Dog while youre at it. fun stuff.
Caution: the following is some beta regarding ER, the second clip in the roof is not that bad if you stem way out right, and have the lip-fingerlock with your right hand.
The slab, as well as the start, are much trickier than they look. I think the roof overhead gives the illusion that this section isn't very steep. 12b/c seems about right... we thought it was harder than the crux of Global Gorilla.
