From Paria Contact Station on 89 we headed back toward Page for about 2 miles...a guess...it's on the North side of the road. Clearly signed as Cottonwood Rd. We followed this well maintained dirt road for 14.2 miles to TH labeled Hackberry Canyon. Go down into wash one third of a mile down stream to a box canyon. Cairns will direct you to a steep single track that goes up about 200 feet very quickly. Follow cairns to hillside covered in yellow stone. I'll post some pics.
