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.
This is up to a 140 foot high buttress or rib of rock that connects with Sherwood Forest across the creek from the Riviera & Bihedral about 7 miles upstream from the Elephant Buttresses/Dome Rock area. It is initially less than obvious that it is a separate rock unless you are Boulder Canyon cognoscetti or until you peruse R. Rossiter's 1999 Boulder Canyon guidebook. Apparently there have been old routes done or attempted low on its steep W face. Since this original post, there has been some lines with bolts and gear added. Certainly, from a distance, evidence of such lines or attempts is difficult to discern. However, a shallow dihedral on the NW edge draws the eye. The less-steep North face also invites the adventuresome but has more lichen.
Expect some lichen and loose rock if you explore here. There is room for more lines for those willing to explore. Expect some shade.
You can descend off to the East on steep slopes. No anchor currently exists on its top.
Several new routes were added in the fall of 2005.
Go to Boulder. Drive W on CO Hwy 119 (aka Canyon). Drive W about 7 mi upstream past Elephant Buttresses/Dome Rock. Park in a nice pullout with some shady trees on the S side of the road below the Bihedral. Walk 150 yards downstream to a tyrolean traverse that starts on a big flat boulder and goes to a big tree on the far side. Cross the tyrolean and head left on a trail heading downstream. After a few minutes you'll reach Witches' Tower near the route Romancing the Stone. Just uphill and right from this is Sherwood Forest.
We did a couple of routes here one day after making a fairly comprehensive tour of Sherwood Forest. I thought the two climbs here were better than almost everything at SF. Remarkable that this cliff which is passed on the approach to SF went ignored for so long.
