Access:
1. The best legal access is from the backside. Go to the second dirt road, Rainbow Springs Rd, one mile up Lovell Canyon Rd from Hwy 160 and turn right. Park several miles up at Rainbow Springs (or as far as the road goes). Most cars can make all but the last part of this road. Hike east over the Keystone Thrust.
2. A few hundred feet on the east side of Mt Springs Pass turn north on Mater Mea Pl. The road immediately splits three ways, take the right fork up the hill and park in a wide spot before the cell tower. Continue on the road which quickly morphs into an unofficial trail to the Keystone Thrust Fault and along the ridge to the back of the canyon, a superb hike in it’s own right and a long approach.
3. Park at First Creek, hike to the base of the escarpment and cross country to the canyon. Spring Mt Ranch owns the entire mouth of the canyon so, to avoid trespassing, check the map and make sure you’re up high enough to avoid their property.
