This site is not operated by BLM. It is within the Kofa National Wildlife Refuge (USFWS). Call them at (928) 783-7861. It is dispersed so first come first serve. Road from Hwy 95 is rough and not recommended for small cars. 14 day stay within the calendar year. No long term and no facilities. Oct. thur March is best time. The area is the only location to collect anything on Kofa. No tools allowed, hands only. 10 specimens or ten pounds which ever comes first is the collection limit per calendar year. Get a brochure at the kiosk when you enter the Kofa, it has the public use regulations and a map.
Only keep your limit and pictures and memories. Wilderness values and leave no trace practices are best way to be.
On the refuge. Can collect crystals off the hill.
