Access Issue: Falcon Nesting Closure at Castle Rock Details


This route is rated 5.7R and is not for the meek. Start at the lower far left side of mammoth rock and follow the arete (5.5). Sling small tree on the way up (last pro for 30 feet) and head right toward crack. Place cam (.5"-.6") and move up to next and last bolt. Head toward chimney and belay in cave. Start up chimney which takes gear well for the first half. The second half can be marginally protected with 6" to 8" pro. Sling tree for anchor at top.
