Grant County, OR Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Grant County, OR — built for the field.
Grant County forms a critical section of Eastern Oregon's historic Blue Mountain gold belt. Mining in the region erupted in July 1862 with the major placer discovery at Canyon Creek, turning Canyon City into one of the largest gold boomtowns in the Pacific Northwest. Today, federal public domain lands across the county are managed primarily by the BLM Prineville District alongside the Malheur and Umatilla National Forests.
The local geology features accreted Paleozoic metasediments and Mesozoic ultramafic rocks intruded by granodiorite dikes and quartz fissure veins. Heavy placer gold eroded from Little Canyon Mountain and the Strawberry Range into the gravels of the John Day River basin, including its North and Middle Forks. Historic dredge tailings still line the John Day Valley, while quartz veins supported hard-rock lode districts near Granite, Susanville, Quartzburg, and Greenhorn.
Prospecting in Grant County requires checking boundary lines due to a mix of public lands and private valley holdings. Federal public domain ground across Forest Service and BLM territory is open to mineral entry unless specifically withdrawn. However, gold-bearing waterways like Canyon Creek, Dixie Creek, Granite Creek, and the upper John Day River contain dense clusters of active unpatented placer and lode claims.
Utilizing an active Grant County mining claims map links prospectors directly to live BLM MLRS records. Overlaying current claim boundaries onto topographic, satellite, and surface management maps allows users to identify open public domain ground, check claim serial status, and navigate backcountry access routes without trespassing.

Staked Maps isn't crowd-sourced guesswork. Active and historical claim boundaries are parsed directly from the Bureau of Land Management's own MLRS/LR2000 case-recordation system — the same records BLM state offices use internally — and kept in sync with our database on a regular schedule. Rockhound Hotspots draw from the USGS Mineral Resources Data System (MRDS), cross-referenced by material so you can see exactly what's been found at a given site. For legal filings, always confirm current status directly with your BLM state office of record; Staked Maps is a research and navigation tool, not a substitute for the official record.
Directly from the Bureau of Land Management's official MLRS/LR2000 case-recordation records, synced into our database on a regular schedule — not scraped or crowd-sourced.

Paid plans add more states plus premium data like full legal descriptions, historical claims, offline downloads, and Rockhound Hotspots.
Active claims currently have valid, in-good-standing filings with the BLM. Historical claims are expired or closed filings — still useful for understanding an area's mining history and past activity.
Free users can search by county. Paid plans add search by claim serial number, plus each claim's full legal (aliquot) description and BLM records link.
A premium map layer of known mineral and gem collecting sites — sourced from USGS records and labeled by material where available (e.g. turquoise, opal, jasper) — for rockhounds looking for their next find.
