Millard County, UT Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Millard County, UT — built for the field.
Millard County occupies a sweeping desert basin in West-Central Utah, stretching from the Sevier Desert and Sunstone Knoll out across the Cricket, House, and Confusion mountain ranges. Internationally renowned among rockhounds for Sunstone Knoll sunstones, Antelope Spring trilobite beds, obsidian, and localized placer gold washes, the region draws gemstone collectors, fossil hunters, and desert prospectors from across the nation. Expansive public domain lands managed by the BLM Fillmore Field Office offer open space for surface collecting and mineral scouting.
Geologically, Millard County features a complex environment shaped by Paleozoic marine sedimentary formations, Tertiary volcanic eruptions, and Quaternary basaltic lava flows. Silica-rich volcanic flows created Sunstone Knoll, where golden labradorite sunstone crystals weathered out of basaltic pockets. In the House Range, Cambrian limestone beds preserve world-famous trilobite fossils, while hydrothermal fluids in mountain faults deposited fluorite, copper, and localized placer gold in dry desert washes.
Navigating Millard County rockhounding requires clear property boundary tracking. While designated areas like Antelope Spring feature commercial fee-dig quarries alongside open public domain collecting zones, surrounding public lands contain active unpatented mining claims and private agricultural ranches. Referencing an active Millard County mining claims map enables field collectors and prospectors to check current federal BLM records, verify open public domain ground outside active claim lines, and explore desert basins with complete confidence.

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 2,992 active and 24,146 historical mining claims in Millard County, UT, plus 603 Rockhound Hotspots — synced on a regular schedule directly from the BLM's own MLRS records.
