Lemhi County, ID Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Lemhi County, ID — built for the field.
Lemhi County stretches along the eastern border of Idaho against Montana, framed by the Beaverhead, Lemhi, and Salmon River mountain ranges. Famed for the historic 1866 Leesburg placer gold rush and the strategic Idaho Cobalt Belt, the county encompasses extensive public domain territory managed by the BLM Salmon Field Office and the Salmon-Challis National Forest. Modern gold panners, suction dredgers, and mineral collectors explore dry washes, mountain creeks, and alpine gulches across this mineral-rich region.
Geologically, Lemhi County occupies a complex tectonic zone featuring Proterozoic Lemhi Group metasediments, Mesozoic granitic intrusions, and Tertiary volcanic structures. Hydrothermal fluids deposited gold-bearing quartz fissure veins, polymetallic copper deposits, and stratabound cobalt-copper-gold mineralization along the 34-mile Idaho Cobalt Belt. Weathering broke down hard-rock vein outcrops, concentrating heavy placer gold across expansive alluvial gravels in Wardboro, Napias Creek, Gibbonsville, and the Salmon River canyon.
For rockhounds and lapidary enthusiasts, Lemhi County offers outstanding mineral collecting. Public domain lands yield specular hematite, quartz crystals, fluorite, epidote, jasper, and agates. Successfully prospecting in Lemhi County demands accurate land boundary verification. Active unpatented placer and lode claims line major gold-bearing streams and critical mineral zones, intermingling with private ranches and wilderness areas. Utilizing a live Lemhi County mining claims map enables panners and detectorists to check current BLM MLRS records, differentiate claim boundaries, and locate open public domain land open to mineral entry.

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.
Yes. The free tier gives you the interactive claims map, land ownership overlays, and basemap layers for your current state, auto-detected via GPS — no subscription required. 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.
Staked Maps currently tracks 7,309 active and 41,777 historical mining claims in Lemhi County, ID, plus 1,030 Rockhound Hotspots — synced on a regular schedule directly from the BLM's own MLRS records.
