Metal Detecting in Idaho
Idaho's gold prospecting heritage (especially the Salmon River and Boise Basin), vast BLM and Forest Service lands, and deep mining history make it a strong Western detecting state. Cultural protections apply.
Legal landscape
Rules in Idaho
Idaho state parks generally permit detecting in designated areas with park staff approval. Idaho Department of Parks and Recreation administers policy.
BLM and Forest Service lands generally permit casual recreational detecting and prospecting subject to ARPA and mining claim rules.
NPS units (Yellowstone partial, Craters of the Moon, Hagerman Fossil Beds) are restricted.
Terrain & climate
