About 67 percent of Utah’s lands are managed by the federal government. Most of this land is open to collecting except for National Parks, National Monuments, American Indian lands, military reservations, dam sites, and wildlife refuges.
Bureau of Land Management (BLM) Lands:
Except where posted or on developed recreation sites, the casual collector may collect reasonable amounts of rocks, minerals,gemstones, invertebrate and plant fossils if collection is for personal, non-commercial purposes. Surface disturbance must be negligible.
Collection of large quantities or for commercial purposes requires a permit from the BLM. Commercial collecting of fossils is not allowed. Use of explosives and/or power equipment is forbidden. You may collect in wilderness and wilderness study areas so long as there is no surface disturbance.
Petrified wood may be collected for personal use up to 25 pounds plus one piece per day up to a maximum of 250 pounds per calendar year. Use of explosives and/or power equipment is forbidden.
Collectors wishing to resell their petrified wood specimens must obtain a permit.
