Park County, WY Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Park County, WY — built for the field.
Park County occupies the rugged northwest corner of Wyoming, framing a dramatic alpine landscape that stretches from Cody and the Absaroka Mountain Range to the eastern border of Yellowstone National Park. Celebrated for historic hard-rock gold and silver mines in the Kirwin and Sunlight districts, alongside Wood River placer gravels, the county draws panners, metal detectorists, and mineral collectors. Public domain lands managed by the Shoshone National Forest and the BLM Cody Field Office provide accessible mountain ground for recreational exploration.
Geologically, Park County is dominated by the Absaroka Volcanic Supergroup—a massive Eocene volcanic complex featuring thick breccias, lava flows, and intrusive stocks. Hydrothermal activity injected gold-bearing quartz fissure veins, silver-lead-zinc orebodies, and porphyry copper deposits into volcanic host rocks around Kirwin and Sunlight Basin. Glacial carving and steep mountain stream erosion weathered these hard-rock lodes, sweeping placer gold into alluvial gravels along the Wood River, Greybull River, and Clarks Fork.
Beyond precious metals, public domain terrain across Park County yields exceptional rockhounding specimens. Weathering of volcanic ash beds produces Wiggins Fork agates, chalcedony geodes, jasper, and petrified wood. Navigating Park County prospecting demands accurate property boundary verification. High-yield river stretches and historic mining camps host active unpatented placer and lode claims, tightly interlocking with private ranches, national park reserves, and designated wilderness areas. Utilizing an active Park County mining claims map enables panners and rockhounds to check live BLM MLRS records, verify open public domain ground, and navigate mountain drainages legally and safely.

1890s Kirwin & Sunlight Gold Discoveries: Prospectors struck gold and silver in the high Absaroka Range in 1892, establishing the Kirwin ghost town and Sunlight Mining District.
Absaroka Volcanic Supergroup Geology: Mid-Eocene volcanic caldera eruptions and granodiorite intrusions injected rich hydrothermal gold-silver quartz veins and porphyry copper deposits into volcanic breccias.
Wood River & Greybull River Alluvial Placers: Glacial runoff and high-gradient stream carving eroded hard-rock lodes, concentrating placer gold flakes and nuggets along Wood River and Greybull River gravel bars.
Wiggins Fork Agate & Petrified Wood: Volcanic ash beds and silica-saturated fluids formed renowned lapidary deposits, yielding colorful Wiggins Fork agates, jasper, and agatized petrified wood.
Shoshone National Forest Access: Vast mountain acreage across America's first national forest offers public domain access for recreational gold panning, sluicing, and surface gem collecting outside active claims.

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 134 current federal mining claim/site records and 2,823 historical claim records from BLM MLRS, plus 58 Park County, WY 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.
