Land & collecting status
Generally open to casual rockhounding
Most public-tagged spots sit on BLM, U.S. Forest Service, or other federal land where reasonable hand collecting of common rocks and minerals is allowed. Confirm posted rules and active mining claims before you dig.
Access note: The free town-owned Schmid Preserve in Edgecomb holds the historic Mount Hunger quarry pits along its trail network. Preserve rules ask visitors to stay on existing trails, so confirm the current collecting policy with the town and limit yourself to loose surface material.
Public-land rules vary by agency, season, and field office. The RockHoundR app pulls live BLM, USFS, NPS, and tribal overlays so you can see exactly which agency manages the ground at this spot.

Geology at Edgecomb Quarry (Schmid Preserve)
