Geology at McVay Rock State Recreation Site

This spot sits on surficial deposits, mapped as mixed glacial sediment, marine terrace, beach sand, gray; mineralogy: quartz rich, mixed fluvial sediment, and dune sand that formed within roughly the last 3 million years. Reworked sediments like these can carry fossils eroded from older beds upstream, typically as rolled bone fragments, teeth, and shell material.

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.

Sources & verification

Spot details combine the public RockHoundR location dataset, normalized mineral labels, agency land-status checks in the app, and community submissions. Coordinates are approximate until verified in the field.
