Park County, CO Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Park County, CO — built for the field.
Park County encompasses the expansive, high-altitude basin of South Park and the surrounding slopes of the Mosquito and Front ranges. Famed for historic placer gold diggings around Fairplay and Alma alongside world-class mineral deposits, the region attracts gold prospectors, suction dredgers, and lapidary collectors. Public lands managed by the BLM Royal Gorge Field Office and the Pike-San Isabel National Forest offer vast space for small-scale placer prospecting and gemstone collecting outside active claim lines.
Geologically, Park County features complex structural faulting, glacial deposits, and intrusive igneous activity along the Colorado Mineral Belt. Glaciers and high-gradient streams weathered gold-bearing quartz veins from the Mosquito Range, creating massive moraine and alluvial placer deposits along the Middle Fork of the South Platte River and Tarryall Creek. Meanwhile, granitic pegmatites and oxidized ore zones yielded renowned gem specimens, including sweet-pink rhodochrosite crystals from the historic Sweet Home Mine near Alma, sherry-colored topaz in the Tarryall Mountains, smoky quartz, and fluorite.
Successfully prospecting in Park County demands accurate boundary verification. Major placer drainages and gemstone districts contain dense concentrations of active unpatented lode and placer claims, intermingling with private patented ranches and municipal water reserves. Leveraging an interactive Park County mining claims map enables panners and rockhounds to check live federal records, confirm public domain availability, and navigate high-altitude prospecting ground safely and legally.

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 640 current federal mining claim/site records and 25,619 historical claim records from BLM MLRS, plus 443 Park County, CO 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.
