Tyler on Brass Monkey, Hidden Boulder


Ironically, the Hidden Boulder is one of the biggest of the Hillcrest boulders, but that doesn't prevent it from being hidden as you approach it. But once you get there you'll find numerous problems with a few of them being extremely highball. The (downhill) side of the rock is where you'll find the highball stuff on vertical faces, and the steeper stuff is uphill from that and much shorter.

Getting There 

From the Saddle Boulders, take the well-maintained trail above them up hill to the right. The trail ascends a steep slope then turns slightly to the left going to the top of the hill. Stay on this trail until you see the hidden boulder on your right about 50 feet off the trail. You can't miss it.

your f.a. info is wrong again guys - maybe you should just leave the f.a. info out if you're not sure rather than ASSuming! here's the correct info before i forget:

- "gimme my forty sucka" was put up by my friend sean brady around the same time we developed the "cow boulder" and i did the problem "space lord" (V1) on "the mother".

-"natural disaster" was put up by mr. rough the same day i did f.a. of "brass monkey" (V2) on the same boulder.

I just started coming out here and am kinda new to the area, can somebody give more clear instructions on how to get to this boulder? Thanks!

VV Pkwy & Browns Vally Pkwy, go west on VV Pkwy. Two ways to get there from here:

#1: 2nd street (Hillcrest) go right. Go straight through a slight left bend. At end is a sharp 90 deg left turn. In front of you will be a small draw with 2 large trees and a boulder (lots of good problems). OK here is where it will get a little confusing. Directly across the stream bed from the boulder is a access gate. Go in here and turn left and start following the trail up hill. This will weave between many boulders with a lot of problems. Keep going till you cross back over the small creek bed and get past the initial cluster of boulders. You will start up a long straight trail pointed straight towards 2 big boulders (Saddle Boulders). More awesome problems! Go around to the right and at the ridge trail (large) go right. Go up the steep hill and at the top turn left to stay on the ridge. About 50 yards look right in the meadow. That's the Hidden Boulder aka Sean's Boulder.

#2: Park by Boxcar Woody boulders. Go through access gate to get behind the BW Boulders then follow the steep trail straight up to the ridge. You come out right by the Saddle Boulders. Turn left on the ridge trail. Up the steep hill. Left at top. Look right after 50 yards. That's the Hidden Boulder.

Thanks for the beta, Rough! Finally got the chance to go look for it and sure enough found it! One more question, on the Saddle Boulders, is there a name for that crack?

It's just called the Y crack. I think more people refer to it more as the Why crack though. I like it. It's easy but you get a little offwidth, a couple fist and hand jams. Be a bit jagged if you OW skills suck. You can climb the face moves and avoid any crack climbing all together. Pretty much V0 either way I think.

Sweet, thanks, just wondering because it wasn't listed as a problem, although it is a fun one!

lowball, scrunchy problems on the short left side overhang. kinda fun when you're too sketched to climb the highballs. :)
