Rock Hounding Code of Ethics The rock hound should determine if the site selected is located within the National Forest Land. It is important to find out if rockhounding is legally permitted in the area. The rock hound should also find out if the mineral rights in the site are privately owned. The above information will be available with the local District Ranger Offices. Semi-precious stones, mineral specimens and common invertebrate fossils can be collected from public lands in reasonable quantities for personal use. Vertebrate fossils can be collected only with requisite permits. Collection of rock materials for commercial use is prohibited. No mechanized tools or explosives can be used during rock hounding. Only shovels, picks, chisels, rock hammers and crowbars are allowed. Most importantly, every rock hound must solemnly adhere to the Rock hound's Code of Ethics to ensure that the entire rock hounding experience is a pleasant and memorable one for everyone involved in the adventure.
