Virgin Canyon
On the crux of Don Quixote 5.11d.
Ben busts out a big move on the Ripped wall.
This is the only major valley on the north side of the main canyon of the Potrero. Deep and shady, it offers respite from the sun on hot days. Deservedly popular, it contains several sub-areas, each with good climbs. This area was one of the first bolted at the Potrero, which helps explain why some of the bolting is a bit sketchy. But don't let that discourage you. You may want to bring some medium nuts to augment the fixed pro.
Strokin' the Bishop 11c, 3 pitches. Climbs a giant tufa on the amazing Ripped Wall located a bit uphill of the previous routes. All the routes on this clean, solid, off-vertical wall have good rock, although some have sketchy pro.
Recommended Routes
Don Quixote 11d. An ultra-classic, climbs a smooth-sided dihedral requiring the kind of stemming technique one would normally use on granite.

Mugre Mugre 10d. Once you get over the 9 meter 5.8 runout to the first bolt, the rest is quite delightful - pocket climbing on an off-vertical wall.

Mi Vida Loca 11c. This devious route is located on the Flatirons, on the north side of the canyon. Short but pumpy.
