2014 Update: The U.S. Forest Service has reopened Eagle Rock and Security Risk climbing areas in Boulder Canyon which have been closed since Feb. 1 to protect golden eagles during their nesting season. Blob Rock and Bitty Buttress areas remain CLOSED.
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.
The Lion's Den is located eight miles up Boulder Canyon just past Boulder Falls. Park at the pullout on the right at tne obvious mine shaft. The cliffs offers about five routes that are mostly crack climbs and one sport route. The climbs are short and face south.
This route is graded 5.9 in D'Antonio's guide and by Rossiter's too, but I thought it was a little harder, maybe 10a. The crack is fairly large for hand jams (Rossiter does call it a fist crack) except in the back of it if you reach way far in. There are face holds in a few spots but not many. This is good because using just the crack would be very difficult. The route protects well yet it was a shock to find something harder than 5.9. Maybe I was just having an off day....[more]Browse More Classics in CO
