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.
This climbs a rising traverse on a dike just out of the river. The first pitch can be done during low tide. The name refers to the result of trundling a large block just above the first belay and one just below it.
Pitch 1: There is a fun move at the first bolt. The crux is at the 4th bolt. It can be easier 5 feet right of 4th bolt, but we did not clean it that well.
Pitch 2: Begin just left of the anchor. Short cruxes are encountered at each bolt. The crux is at 5th bolt when the climb steepens. A red Alien may be placed before the 5th bolt. Originally the climb went 25 feet above the current anchor, but that just created rope drag and poor communication.
You can either lower/rappel to the river or traverse right into the woods at the level of the first belay anchor, depending on the water level.
Gets good early morning sun if the rest of Castle Rock is too cold.
Begin 20 feet right of Subterranean Homesick Blues. You can use the first bolt of SHB as a directional belay anchor so the belayer does not get pulled into the water in case of a fall. If the water is too high, the top of the first pitch can be reached by traversing in from the right.
Pitch 1: 5 bolts to a 2-bolt belay. Pitch 2: 5 bolts plus optional red Alien to a 2-bolt anchor with chains.
Routes right of The Big Splash= from a high ledge a seam up to a hand crack is "Flaming Dog Poo" 5.10ish? (hard start) further right is a nice overhang to dihedral that I cleaned and tried a couple times, then abandoned because somebody else put twelve bolts on the thing.

Dirty, discontinuous, and a few nice sections. But not enough to make a nice route of it.
