BETA PHOTO: Island Rock, The Dome and Elephant Butress as seen...
Seasonal Raptor Closure MORE INFO >>>


This is a chunk of fractured granite that many folks pass as they go off to play on The Dome or Elephant Buttresses. Apparently this crag was developed as a drytooling locale. Occasionally, folks are seen here bouldering, TRing, drytooling, or occasionally leading. Since we're on a reorganization of BC & there's a route for this rock listed under a different crag, we'll create this for clarity. There are routes on all aspects of this rock. There is a bit on the N or NE aspect which seems to be particularly popular for beginners.

The route(s) in our database include:

A. Independent, 7 or M2?, 1p, 50'.
B. Unknown II aka The Broken Wing, 9- X or M4?, 1p, TR.
C. Destroyer, 10 or M5?, 1p, gear.
D. Unknown, 7+ PG-13 or M2?, 1p, 50'.

Getting There 

Park in either the small parking area on the N side of the road as for The Dome or Elephant Buttresses OR park in the huge parking area on the S side of the road, cross the road, and you're virtually there.

This route is actually on Rock Island 1, and is pretty much right in front of the bridge. This route is also very easy to toprope, but you will need long runners to reach over the lip from the anchors.The starting point for this is about 10m from the 5.7 route called Independent Route which is in Fred Knapp's Front Range Topropes. Start under the roof, moving quickly left and up the outside edge of the roof, reach up to a good hold with your left hand and head for the sloping, right-an...[more]   Browse More Classics in CO

I lost a BD ATC-Guide two weeks ago or so up in Boulder Canyon. I think I lost it around the Dome/Elephant Butresses area (but could be somewhere else). I'm just a poor college kid with no money and now no belay device. If you found it and returned it, I would be extremely grateful and would be more than happy to reward you with some beer.

It should be noted that this crag was first developed about 20 years ago as a DRYTOOLING practice area. Several of the top rope anchors were placed for this purpose....

People should not freak out if climbers show up with crampons and ice tools and begin using these tools on the rock.... Rock climbing is a secondary sport here.
