Colorado Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Colorado — built for the field.
Colorado stands among the nation’s premier mineral exploration states, anchored by the iconic Continental Divide, the Front Range mineral belt, and the volcanic San Juan Mountains. From the historic placer channels of the South Platte and Arkansas Rivers to high-altitude quartz lodes in the Rockies, thousands of active Colorado BLM mining claims encompass productive placer gravels, hard-rock vein networks, and world-class mineral deposits. Federal domain lands managed by the Bureau of Land Management and the United States Forest Service provide vast territory for panners, detectorists, and lapidary collectors.
The state’s complex geological evolution underpins its legendary mineral wealth. Laramide-age igneous intrusions, complex faulting, and intense hydrothermal activity injected gold-bearing quartz veins, silver-lead-zinc orebodies, and molybdenum deposits across ancient Precambrian metamorphic host rocks. Subsequent glacio-fluvial erosion washed heavy placer gold into mountain drainages and broad alluvial basins. Beyond precious metals, public land across Colorado yields prized gemstones and specimen minerals, including aquamarine, amazonite, smoky quartz, rhodochrosite, barite, topaz, and agate.
Navigating Colorado prospecting requires precise boundary verification. Unpatented placer and lode claims closely line high-yield rivers and historical mining districts, interlocking with private patented holdings, state trust lands, and designated wilderness areas. Utilizing an active Colorado BLM mining claims map enables prospectors and rockhounds to examine live federal records, distinguish active claim boundaries from open public domain ground, and explore backcountry mountain districts safely.

Official Prospecting Resources for Colorado
What it is: The official federal Bureau of Land Management Colorado State Office portal governing public domain mineral entry, land records, and unpatented claim filings across Colorado.
Use case: Submitting new location notices, paying annual federal claim maintenance fees, filing Small Miner's Maintenance Fee Waivers (Form 3830-002), and getting filing assistance from the Denver Public Room.
What it is: The official state geological survey providing state geological maps, mineral resource reports, and historical mining district data.
Use case: Accessing state geological publications, researching historical mining district records, downloading digital geologic maps, and evaluating state mineral land classifications.
What it is: The primary state-level portal for the Bureau of Land Management in Colorado, overseeing 8.3 million acres of public domain surface land and over 27 million acres of subsurface mineral estate across the state.
Use case: Accessing district and field office contact directories, verifying regional fire restrictions and land closures, reviewing statewide land use planning projects, and obtaining general administrative information for public land entry across Colorado.

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 11,633 active and 287,993 historical mining claims in Colorado, plus 16,266 Rockhound Hotspots — synced on a regular schedule directly from the BLM's own MLRS records.
Yes — the Colorado claims map covers the entire state today, including Teller County, Chaffee County, Clear Creek County, Gilpin County and Park County. Dedicated pages for each are coming soon.
BLM Colorado State Office Mining & Minerals is Colorado's primary office for filing and researching mining claims — see the Official Filing & Information Links section above for the direct link and more resources.
