Located in the Pueblo Canyon wash near North Road, Pueblo Canyon features high-friction tuff that is in many places choss. Where it is not choss, there is generally fun, slopey, movement with sandy landings.
The area has seen a bit of a revival of late. It was originally explored by Luke Laeser and company in the late 80's but recent activity by Miguel Hoffman, Colin McFarland, Shibli Fazal, Rob Hilko, Scott Beguin, Jason Hundhausen, Nate McDowell, and I think Ken Kisiel, and a couple more people - including myself, has brought the area back into local consciousness.
The area features many holds, so it is good for contrivances. There are obvious lines, but something harder is probably nearby.
From everywhere outside of Los Alamos, go there and take Diamond Drive north. Shortly after the gas station on the left, hang a left on North Rd. (the sign is hard to see, but its immediately after Ridge). Go to the bottom of the wash and park on the right. Walk across the street and the bouldering begins just north of the Roadside Boulder (I hereby dub) with one line that currently needs cleaning (project V6?).
The main area is about 5 minutes up the wash, but there appear to be several fun diversions on the walls lining the approach.
Another taller boulder is located 100' past the main area.
This area is known to most locals as the North Road bouldering Area which has two sides to it(east of the road and west of the road) The real Pueblo bouldering area is east of Diamond Dr. next to the old Pueblo Middle School, in Pueblo Canyon proper, and parts of School Canyon.
Fun area, but fragile...which was part of the reason its gone un-posted. don't fully trust any holds in pueblo canyon and climbing after rain seems to increase chances of holds breaking. also these climbs were all probabaly done in the eighties by some of the many climbing characters that have roamed this town, before the canyon had filled with pumice and was much taller. Ive always called it the water?fall boulder.
Kudos rock climbers! For a duration of the 80's this went unnoticed because it was hidden by such greenery as trees and brush, obscured by fast driving, and probably as fragile because it was the same rock but seemingly somewhat taller in this area where the canyon met N Road. I was younger and smaller then, so it's a matter of perception. I used to walk my BMX bicycle up the hill between the houses and never saw any chalk. It is indeed solid as a rock in particular places that I only know of as around the Old Pueblo Middle School or New Office Building. Also, behind the church starting up Conoco Hill, and way further downstream in P Canyon on possibly a topo. To get to lower P. Canyon you have to visualize yourself in relation to the ground and walls in total darkness in this peculiar new tunnel underneath the land bridge. Goodbye.
