Access Issue: Current San Diego County Advisories Details


Overseeing the landscape is the patriarch of Mt. Woodson, The Uncertainty Principle. Some despise it while some revere it, but all respect it! From the gate, it is located about a half mile up the road, capturing the interest of all who pass by it. Continue up the road past the roadside route Rock The Boat and take a left turn trail to easily access. The route involves stepping off a boulder on the right side climbing straight up to the top. The crux is getting past the initial moves.
Highly recommended.


TR, bolts. Set-up is via a two bolt lead up the north face (low-angled face in the picture).

At some point (maybe more than once) this route has been bolted for a lead. This was never deemed appropriate, and was always cleaned of such hardware. There is one old bolt left of U.P. which remains. Feb 12, 2006

The TR access route actually has 2 bolts. Quickest way is to yard up on the bolt to get over the lip. 1 more bolt protects the face to the top. You can lower back down and clean it off, to save the trouble of your follower coming up. Sep 28, 2006

That "yard up" start actually goes at 5.10b and the face at 5.6 Apr 3, 2007

Word had it "back in the day" that that "remaining bolt" was placed to aid in a hooking ascent of the entire face which started underneath the bottom apex that rests on the grounded stone.
"Troy" and "Marty", out of Ramona, did a good job in bolting Uncertainty Principle in the late 80's, early 90's?. Too bad it was taken down, IMOHO! Jul 4, 2007
I can't imagine anyone not liking this sucker! One of the best climbs of it's grade and TR only anywhere. For me it is in the top 5 best climbs in the San Diego area for sure! Mar 26, 2009

When comparing this to Eric's Face 11b and Seminar Wall 11+ I am in awe of the difference between a letter grade and a + sign lol. Jul 9, 2014
