Hells Canyon (Pittsburg Landing)

Idaho, Idaho·Rockhounding

Rockhounding at Hells Canyon is mixed: a third of the NRA is Wilderness, where collecting is prohibited, and no policy for the rest was confirmed.

  • Hells Canyon National Recreation Area is administered by the Wallowa-Whitman National Forest, with the Nez Perce-Clearwater National Forests co-managing roughly 117,000 acres on the Idaho side — this is Forest Service land, not BLM, despite widespread BLM labeling in rockhounding guides
  • Roughly a third of the NRA is designated Hells Canyon Wilderness, where the Wilderness Act of 1964 prohibits collecting any natural object, rocks included, regardless of quantity
Allowed

Spencer Opal Mines

Idaho, Clark·Rockhounding

Digging for opal at Spencer Opal Mines is a private fee-dig on a patented claim — $75/adult, $50/child — no permit needed, and no mapped free BLM ground nearby.

  • Spencer Opal Mines' tailings-pile dig — $75 per adult, $50 per child under 16 — sits entirely on privately claimed, patented ground; you pay the operator's fee directly, no government permit or reservation is needed
  • No clearly mapped, publicly accessible BLM opal-bearing parcel comparable to the commercial claim was confirmed for this page — BLM's standard casual-collecting allowance applies to genuinely open public land in the surrounding district, but that's a different, unmapped proposition from where most visitors actually dig
