Snohomish County, WA Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Snohomish County, WA — built for the field.
Snohomish County spans a rugged mountain terrain in Western Washington, extending from the shores of Puget Sound up into the glaciated peaks of the North Cascades. Renowned for the rich placer gravels of the Sultan River and historical hard-rock silver-gold mines around Monte Cristo, Silverton, and Index, the county attracts gold panners, detectorists, and specimen collectors. Public domain lands managed by the Mt. Baker-Snoqualmie National Forest offer regulated space for recreational prospecting and mineral hunting outside active claim lines.
Geologically, Snohomish County occupies a complex tectonic zone within the Cascade magmatic arc. Mesozoic metamorphic rocks and granitic plutons were fractured by fault systems, where hydrothermal solutions injected pyritic quartz veins laden with gold, silver, copper, galena, and sphalerite. Deep glacial carving and high-gradient river erosion weathered outcropping veins, concentrating placer gold across alluvial gravel bars along the Sultan River, Skykomish River, and South Fork Stillaguamish River.
Beyond precious metals, public domain slopes yield collectible mineral specimens, including almandine garnets, quartz crystal clusters, jasper, chalcedony, and staurolite. Successfully prospecting in Snohomish County requires exact property boundary verification. High-yield river corridors and historic mining camps contain active unpatented lode and placer claims, interlocking with private timberlands, municipal watersheds, and state parks. Utilizing an active Snohomish County mining claims map enables panners and detectorists to inspect live federal BLM records, verify open public domain ground, and navigate mountain drainages legally and safely.

Staked Maps isn't crowd-sourced guesswork. Current and historical claim boundaries are parsed directly from the Bureau of Land Management's Mineral & Land Records System (MLRS), which replaced the legacy LR2000 mining claim system in 2021, 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 (Mineral & Land Records System) case-recordation records, synced into our database on a regular schedule — not scraped or crowd-sourced.
Staked Maps displays the status reported by BLM. Records with a case disposition of Active are labeled Active; historical records come from BLM's closed-claims dataset. These statuses are research information, not a Staked Maps legal determination of claim validity, discovery, ownership or compliance. Verify the current record through MLRS before acting on it.
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.
Staked Maps currently tracks 101 current federal mining claim/site records and 3,114 historical claim records from BLM MLRS, plus 408 Snohomish County, WA mineral-occurrence records derived from USGS MRDS.
A premium map layer of documented mineral occurrences, prospects and mines sourced from USGS MRDS and labeled by material where available. These records are research leads, not a directory of verified public collecting sites.
