Nobody can answer this question with a lookup. Claim status is not a fact that sits in a downloadable dataset: it lives with the BLM and a county or borough recorder, and it moves between the dated snapshots anyone publishes. What software can do is the step before that call. It can show which public records exist for a piece of ground, say how old each record is, and keep a dated note of what was already checked, so the research still holds up three months later.
That is the job Gold Story does. (It appears on the App Store as Prospecting Log: Gold Story; it is an iPhone app from our studio, Studio AM.) It maps 75,000+ historic USGS gold records, downloads dated BLM claim-record packs for 11 covered states, keeps a timestamped research log, and then works as a GPS field journal once you are standing in the water.
Why “is it claimed?” has no one-tap answer
Claim data is a public record, and public records lag. A location notice filed last week may not appear in a dataset you downloaded last month. A claim shown as active may have lapsed. A claim shown as closed may have been relocated by somebody else since the snapshot was taken.
The geometry is loose too. Claim records are tied to the Public Land Survey System, so what you get is a township, range, section, and often a quarter-section: a reference point, not a surveyed boundary. A dot at that resolution is not something you can stand on.
Then there is the part people miss entirely. Surface access and mineral rights can sit with different authorities, so “nobody has a claim here” and “I am allowed to be here and dig” are two separate questions with two separate answers. An absent record answers neither one.
So: records narrow the search and tell you where to ask. The BLM, the county or borough recorder, and the land manager for that ground give you the answer.
Three kinds of evidence, kept apart
Expensive mistakes come from stacking three different things into one impression of a place. Gold Story keeps them on separate, labeled layers.
| Layer | What it is | What it does not tell you |
|---|---|---|
| Historic USGS sites | 75,000+ gold-related locations from the Mineral Resources Data System: occurrences, prospects, past producers. The dataset is frozen around 2011. | That gold is recoverable there today, or anything at all about who holds the ground now. |
| BLM claim records | Dated active and closed claim records for 11 covered states, with PLSS section or quarter-section references and a visible source date. | Current status, or a legal boundary. A missing record is not permission. |
| Your field journal | What you saw, sampled, and recovered, with your own coordinates, photos, weights, and notes. | Anything about the land status. It is your observation, nothing more. |
Reading down that third column is the useful habit. A historic producer next to a spot with no claim record looks encouraging on a screen and proves nothing. Gold Story’s research leads work that way on purpose: they compare historic producing sites against the claim records you have installed, and stop short of calling any ground “unclaimed.”
What you can actually do before the drive
Open the map and find your area. The low-zoom world map, the detailed US base, the historic USGS records, and a California detail pack are bundled, so that first pass needs no signal. Other region packs and the BLM claim-record packs download once over a connection, then live on the phone.
Then inspect the records rather than glancing at the pins. Each claim record shows its PLSS reference and the date of its source data, which tells you how much to trust it. Refresh the public pack catalog when you are online to pick up newer snapshots.
Then go to the official sources. That means the BLM’s Mineral and Land Records System, the recorder for that county or borough, and whoever manages the surface. We publish a free printable version of that whole sequence at the gold claim research checklist: seven steps, with a notes field for each, running entirely in your browser tab and saving nothing anywhere.
The log is the part everyone skips
Here is the failure mode. You do two hours of careful research in March, drive out in June, and cannot remember which serial numbers you looked at, which page you read them on, or whether you called the district office. So you go anyway on a vague memory, or do the two hours again.
Gold Story’s due-diligence log exists for that gap. It keeps a timestamped record of the claim records you checked around a location, so the research has a date attached to it. Saved field reports can be shared out as JSON (claim serials or names, notes, dates, coordinates), to a destination you pick through the system share sheet.
Claim-change alerts and other reminders are optional local notifications, scheduled by iOS on your device. Studio AM runs no push server and never sees your notification settings.
The other half of the app is the field journal
Once you are out there, the app switches roles. It records finds with weights, methods, photos, weather, and notes; saved spots and waypoints; trips, with an optional GPS breadcrumb trail; and a bearing back to any point you saved. Location permission is optional, and a missing or imprecise fix never stops you from saving a find without one.
There is a “Log a Find” Siri shortcut for when your hands are wet, and a widget showing only the season year, your find counts, the last-find date, and the update date. No coordinates, notes, or names appear in it.
The app also carries 43 lessons on gold basics, reading water, technique, safety, legal checks, and state rules. If you want a sense of that material before buying, the free beginner prospecting guide on this site covers the river-reading and panning part of it: inside bends, the shadow behind durable obstacles, bedrock cracks, gradient breaks, and confluences. When you want to price what came out of the pan, the gold value calculator runs on a spot price you type in, not a market feed we claim to have.
On an iPhone running iOS 26 with Apple Intelligence ready, Apple’s on-device model can structure a find note, recap a trip, or summarize a research lead. Those tools are hidden on unsupported hardware, and the maps, records, lessons, and claim research do not need them.
Offline behavior, privacy, and price
Everything bundled or installed works offline: base maps, historic sites, region packs, claim-record packs, all 43 lessons, and your entire journal. A connection is needed for StoreKit, the first download or refresh of optional packs, links you tap out to the web, and private iCloud backup if you switch it on. Pack downloads pull static files over HTTPS from a public release catalog and carry no journal data, spots, photos, or location. Like any HTTPS request, they do carry the ordinary network metadata needed to deliver a file, such as an IP address and user agent.
There is no Studio AM account, advertising, analytics, tracking, telemetry, or journal server. Private iCloud backup is off until you enable it and then press “Back up now”; it keeps up to three archives of 500 MB each in your own iCloud, which Studio AM cannot read, list, or delete. Export produces a ZIP with the journal as JSON, CSV tables, GPX and KML when locations are included, and your photos. Turn locations off and it strips coordinates and photo GPS metadata; a photo it cannot strip safely is left out and reported rather than shared quietly.
Gold Story needs an iPhone on iOS 17 or later, and its interface and lessons are currently English only. There is no permanent free usage tier. US pricing is a one-time $24.99 purchase that never renews, or $4.99 per month, or $29.99 per year, with a 3-day trial for eligible new subscribers on the two subscription plans. All three give you the same complete app, claim records included. Apple shows eligibility, local pricing, and renewal terms before you confirm. If access ever ends, your existing records stay readable, searchable, editable, deletable, and exportable; only new records and the Pro tools stop.
The full feature list is on the Gold Story app page.
FAQ
Can an app tell me whether a gold spot is already claimed? No. Gold Story’s BLM claim-record packs are dated snapshots with approximate PLSS section or quarter-section reference points, not surveyed boundaries or legal advice. A missing record is not proof that ground is open. Verify current claim status, ownership, access, and local rules with the BLM, the county or borough recorder, and the relevant land manager before visiting or digging.
What is the difference between a USGS gold site and a BLM claim record? They answer different questions. The 75,000+ USGS locations come from the historic Mineral Resources Data System, frozen around 2011, and describe occurrences, prospects, and past producers. The separate BLM packs hold dated active and closed claim records for 11 covered states. Neither layer on its own establishes current legal access.
Does the gold map work with no cell signal? Yes, once the data is on the iPhone. A low-zoom world map, a detailed US base, the historic USGS gold records, and a California detail pack ship inside the app. Other region packs and the BLM claim-record packs need a connection for their first download, then work offline along with the 43 lessons and your journal.
What is a due-diligence log and why keep one? It is a timestamped record of the claim records you checked around a location, kept inside Gold Story. Public records go stale, so the useful thing to preserve is what you looked at and when you looked at it. Studio AM also publishes a free printable seven-step version of that research sequence at the gold claim research checklist, which saves nothing anywhere.
Does Gold Story send my journal or location to Studio AM? No. There is no Studio AM account, advertising, analytics, tracking, or journal server, and your live location is never sent to Studio AM. Records stay on the iPhone unless you make an export or turn on private iCloud backup, and Studio AM cannot read either destination.
What does Gold Story cost? There is no permanent free usage tier. In the US, Pro is sold three ways: a one-time $24.99 purchase that never renews, $4.99 per month, or $29.99 per year, with a 3-day trial for eligible new subscribers on the two subscription plans. All three give you the same complete app. Apple shows eligibility, local pricing, and renewal terms before purchase.
