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.

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 Lakeview

This spot sits on volcanic rocks, mapped as siltstone, dark gray, green brown, red brown, claystone, tuff breccia, ash-flow tuff, light; lithology: dacite, rhyolite, and sandstone that formed roughly 34 to 5 million years ago. Volcanic rock like this is classic geode and thunderegg country: gas cavities in the old flows can line themselves with quartz or agate over time.
