Black Widow Slab is the large rock located just right (west) of Vampire Rock, 8.5 miles up Boulder Canyon. A number of good sport climbs can be found on the clean north face and several ice climbs form on the northeast face during good (wet) winter months. This is a good spot to escape the summer heat and enjoy some quality climbing in a beautiful setting.

Getting There 

Drive 8.7 miles up Boulder Canyon and park in a large pullout on the left across the road from the Boulderado. Head down stream for a couple hundred yards and ford the creek. Hike up a gully and reach a good trail that goes along the base of the rock.


Since the area description above doesn't mention it, the tyrol for Black Widow is actually a little downstream, directly below the Vampire. Angle up and right across the scree field to get to the routes at Black Widow.

Consilience 5.11b/c 6c+ 23 VIII- 24 E4 6a  Colorado : Boulder Canyon : Black Widow Slab
I am going to go out on a limb here. This is one of the best slab route in the area. This climb offers continuous, quality climbing up a near vertical face/slab on knobs and small edges that lead to expose moves out a small overhang just below the anchor. A longer and better version of the "Scientist" with a hard move to gain a ledge near the top. The route starts on the northeast face of the rock just left of the old "Left Side" route. Climb up to the first bolt with caution or just stick-clip ...[more]   Browse More Classics in Colorado

Does anyone know what the sport route is that is just right of Dracula? It doesn't appear to be documented anywhere? I believe it's a Steve Damboise route? Bolted a couple years ago?

While you're at it, what about the one to the left of Dracula?

I believe the route left (the arete?) is Mordred, .14a, FA: Gomez aka Luke Parady, Winter '09.

We replaced the tyrol tonight (thanks for the help Kevin V.!). The old rope junk-show of an anchor with its multiple core-shots from rubbing on the rock has been upgraded with chain to help it last a bit longer.

There are two strands of static that should keep you well out of the creek. The rope was donated by fellow MP'ers. Thanks, everyone!

Since the area description above doesn't mention it, the tyrol for Black Widow is actually a little downstream, directly below the Vampire. Angle up and right across the scree field to get to the routes at Black Widow.

The route list on this page, above, stirs up the murk already surrounding the locations of Kor's three routes on this rock. I don't know where he climbed, but I think that logic supports that "Center" is to the left of "Right Side." And I think that what this list calls "Center" is really "Right Side."

I have climbed (9/23/74) what I believe is "Right Side," all the way to the top. It is an obvious line (5.8 or 5.9) and is what D'Antonio calls "Wired." It begins in the dihedral shared with "Bands of Gold," which contrives to climb the left wall of the dihedral. And it seems to fit with Ament's and Erickson's vague descriptions of "Right Side."

What D'Antonio calls "Right Side" is what Rolofson calls "Wired." This pitch is an unlikely choice for "Right Side." It is relatively inobvious, is hard-to-protect 5.10, and ends at anchors shared with "Smoke Down" (although, yes, you could keep going up).

I have climbed "Bong Session," which ends at bolted anchors at the top of a clean crack. While it may be possible to continue free to the top, there is a less-obvious line above the anchors. I'm not suggesting that Kor would only follow obvious lines. Given my above arguments, however, I'm curious about why Chris Archer thinks "Bong Session" is Kor's "Right Side." Even though bongs (thick pitons) could be useful, I don't think those had been invented by 1961 (just kidding). (See thread on Bong Session.)

Anyway, the use of the name "Center" in the list on this page acknowledges that the first route right of "Bands of Gold" could be one of Kor's three routes.

Today, I toproped the mossy line between Kate Moss and Consilience, using the KM anchors. (One could continue the line upwards on lead, rather than move left to the KM anchors.) It felt like 5.10, although a taller person may find it easier -- or resort to aid in places -- or do some cleaning. I saw only rare opportunities for pro, although you may be able to find placements if you excavate a little of the moss. I did come across an old, rusty ring piton (which seemed solid) at about 80 or 90 feet.

Judicious cleaning has made Kor's Center Route, which climbs past the dead tree between Consilience and Gyromancy, and which sports three rusty fixed pins, enjoyable and protectable.

According to High Over Boulder, "Left Side" (FA: Kor and Bleser, 1961) may follow the line in D'Antonio's guide, left of Kate Moss. It looks pretty scruffy, but there is a potential route.
