Climbs are on the South, East, and North faces.
Ridiculous in Summer. Nice Fall thru Spring.
Mostly good rock, despite the reputation.
Seldom visited. Probably will remain that way. Not the typical, well-manicured routes of Mt. Lemmon.

Park in main parking lot for Molino Campground (same as for "Sunspots Crags")near MP 5. Walk across Hwy. and start up AZ Trail, continuing up canyon on lesser trail before first drainage crossing. The fading trail eventually climbs to the left of a waterfall, at which point you'll be able to see the broad south face of the Stonewall, behind and left of the Lost Wall. Just after the waterfall the canyon takes a sharp right, then a side drainage heads up left. Follow this lesser drainage toward the Thumb and Stonewall.

The south face of the Stonewall has several distinguishing characteristics. On the far left end is an obvious chimney that splits a wall into two pinnacles, (the “Pin There…” pinnacles.) The left pinnacle is orange-ish. To the right of the pinnacles is an inset wall with a series of small, left-diagonalling roofs and a long, right-curving crack (Pagoda Crack). At the top of the wall is a small formation resembling a pagoda. Further right there are 2 huge roofs in the center of the south face. To the right of the roofs, about halfway up, is a large, left-facing corner with a chimney (P.3 of “Cody Wasn’t Here”.) Best to include a double set of cams to #4 for most of these routes, as well as 60m ropes. Zig-zag up to the base of the climb you choose.

For the north and east face routes, diagonal up to the saddle at the east (right) end of the south face.
On the southeast corner is a key feature: a chimney system running the entire height of the wall (~200 feet.) This had 3 rap stations, so it's been climbed by someone out there.
The other climbs probably had not been done, but you never know. Let me know if you have any info.
1 to 2.5 hr. approach.
Double 60 M ropes are best for the east and north face routes, but not absolutely necessary.
