Closed to climbing, Feb 1 - Aug 31 MORE INFO >>>


Barnum is a nice rock high on the mountain with a reasonably short approach and a number of easy but fun routes. Most of the routes are bolted with chain anchors. The 7500' altitude and trees for shade make this a comfortable area to climb when the temps are rising in the valley.

Getting There 

Park in the turnout on the left side of the road about 1/10th a mile before the 18 mile marker. Cross the road and head up the drainage for the obvious cliff. The trail is now pretty obvious and well-marked with cairns.

Climbing Season

For the 6 - Mid-Mountain area.

Weather station 1.5 miles from here

From the top of the trail (Ranger Danger) go left maybe 20-30 feet to where you can see a crack to the right of a short overhanging headwall. The route starts on low angle EASY stuff (5.3-5.4 at most) until it gets to the short overhanging headwall, where it rapidly turns into a 5.9 for 2-3 moves, then gets easy again to reach a huge ledge with chain anchors. Belay the second from the top andrap if you do this one or the drag will rip up your rope...[more]   Browse More Classics in Arizona

Barnum rock is mentioned in the Steiger guide and Squeezing the Lemmon II without any detail. This is in the same area as Gumby wall, but is accessed from the west side. We are calling the west and south face the Bay Lee wall in the route descriptions. GPS coordinates are: N32.40089 W110.69644

In 2008, this area is closed between February 1 and August 31 - for nesting peregrine falcons and Mexican Spotted Owls.

Some fun climbs in here, especially the 5.9..

Suitable for beginning leaders if they have a good lead head, there are some should-not-fall situations, runouts on easy slabs and ledges..

The parking pull out is just before mile marker 18 not after it.When driving up the mountain. I have added a picture of Barnum Rock you can see from the parking area. I hope this helps you find it.

There is another sport route that doesn't seem to be listed yet in the Mountain Project beta to the right of Ranger Danger that feels in the 5.7 range, though perhaps a bit more vertical than many of the 5.7s here. There are chains at the top.

Great area for moderate sport routes. Barnum is great because the approach is short, <5 mins, and hardly has a climbing party there, even when open for climbing. (Of course, see falcon closures.) I suggest climbing here in the morning, as the sun can be very hot. Or even in later fall/winter. Would be nice for a topo/overhead of the area.

Found a gold Black Diamond belay device here on 9/5/10. Is it yours?

I was with a climbing party on 9/4/10, and two different pieces of gear fell from pretty far up on two separate routes. I believe one was an ATC type device, the other was a biner. It's advisable to not use these if found.

From what I can tell from reading all the route discriptions the routes from left to right are:
Sweet Pea
El Diablo
Twin Peaks
Foul Fowl
Beatle Bay Lee
Trail Meets Cliff*
Memorial Daze
Ranger Danger
Ann Bay Lee
No Hope W/O Dope(alternate PW start)
Pizz Whiz

Is this correct? If not please correct. Are there any more routes that are not listed here?

Awesome climbing here for the 5.7 leader. We did some trail work and built some more cairns this weekend.

Wondering who is working routes far left and uphill from main wall. Went today and awkwardly linked two bolts on downhill (right, facing wall) to belay ledge w/skinny tree, then moved btw tower and main wall to vertical climbing ending w/chains. Did not notice the nearly fully bolted route uphill from our start, left side of tower, until rapping down. Whoever this was/is, good job and thanks, noticed lines for a few more possibles here as well.

I'm going to go against the grain and say this isn't the best area for the beginning leader. A lot of no-fall situations and many of the bolts are of a variety that climbing magazine says not to trust (want to say 5/16'' hex heads.)
By 1Eric Rhicard

Pretty sure Ben Burnham put in most of these bolts or was involved so I doubt they are 5/16ths and since I have done them all I would have noticed if they were. I have replaced dozens of older bolts on this mountain and have yet to replace any of the modern bolts I wouldn't have and sometimes did fall on prior to replacing them. 1/4 inch button heads are bad 3/8ths split shanks are bad as are 5/16ths but rarely. Go Climb have fun don't worry. CASA is working on replacing all of the oldest and mixed metal bolts.
