Spectrum Wall is a small formation of high quality rock overlooking Upper Sabino Canyon, directly across the canyon from The Steep. While there are not a ton of climbs, they span across the range of difficulty from 10a to 13d, with something for everyone in between.

Climbs are all west facing. AM shade, PM sun.

Getting There 

Park at Box Camp trailhead, and begin hiking. Follow Box Camp Trail for a few minutes, until you see the large cairn for the Ireland trail. Turn right, and follow the Ireland trail. Pass through the baby pines, and down a small hill.

At the bottom of the hill, the Ireland trail veers right. You will climb over a large downed tree, and pass between two knee high boulders. Walk another 20 feet, and look left for a small trail heading south along the ridge line (while the Ireland trail continues westerly towards the canyon). This is the trail that leads to Spectrum - turn left, and follow this trail.

Follow the cairned ridge line through a sea of fire-damaged trees, and down into a steep gully. Cairns lead you down the gully until the trail crosses the gully at a small pool of water.

Continue across gully, following the obvious trail leading down the steep hillside, until you arrive at the top of the crag. Contour around the right side of the crag, dropping down the gully. Scramble down a boulder, avoiding the big hole, and the gully will deposit you at the left end of the crag.

30-35 minutes down, 35-45 minutes out. Save some juice for the steep hike out.

A striking overhanging arete that climbs as good as it looks. Most of the climb is pure arete climbing, with hands and feet milking unlikely holds on either side of the feature. I had been eyeballing this line for years from across the canyon. I was finally drawn in, and all control was turned over to The Sampler....[more]   Browse More Classics in AZ

Jbak, I was surprised to hear you hiked out here, but never climbed anything. It turned out to be a fun little area.
