Open it and pick a spot. Pins come from named public records, scores use those records, and they cap at 69. Every marker names the record it came from, so you can check it yourself.
Free. No account needed to see a pin or a score.
Spread across 50 states and DC, with sourced places in 133 countries. The deepest data, mining claims, land ownership and river gauges, is United States only.
A honey hole is a specific piece of ground the model scored, not a district and not a rumour. It reads recorded workings, the rock, the terrain and the water, then ranks where the evidence stacks up. Nobody has confirmed a deposit at any of them, which is exactly why the inputs are published.
| What the model reads | Why it matters |
|---|---|
| 3,973 recorded placer workings | Ground that has produced before, and how much came out |
| Bench height above the stream | Measured from LiDAR, not estimated from a contour |
| Inside bends and confluences | Where a river slows down and drops what it carries |
| Host rock and fault control | Whether the setting can produce in the first place |
| Surface ownership and claims | Whether you may legally stand there at all |
| Live gauge flow and burn history | Whether it is workable this month |
US holes name the owner when the record has it, and say whether the ground is open, claimed, private or worth checking first. Worldwide holes do not: there is no global ownership record, so they carry ACCESS NOT CHECKED where the law has not been researched. Scores cap at 69.
Nearby lists holes by distance after you locate or set a home base.
Land status shows when that layer is on and the record exists, with claims, access notes and how many independent records back the spot.
Save the layers on signal. The phone keeps them.
Saved spots stay on this device. An account syncs them across your devices.
Every marker links back to the government record it came from, so you can check it yourself. Pins cite public records. The score is a rank, not a confirmed find.
| Source | What it gives you |
|---|---|
| USGS MRDS & GNIS | Mineral records, place names, documented workings |
| BLM | Mining claims, surface management, PLSS survey grid |
| USGS Water Services | Live flow and the seasonal window for each creek |
| Paleobiology Database | 120,093 published fossil localities (CC-BY) |
| USDA / NIFC / FEMA | Forest ownership, fire perimeters, flood and terrain |
| Wikimedia & Openverse | 1,114 photographs, every licence verified per file |
Nothing. There is no paid tier, no trial that expires, and no card on file.
Every pin, every score and every map layer is open without an account. An account syncs your saved spots across devices, logs your finds and opens the club. Some overlays are United States only.
Not sold, not shared, and no ad networks. No trackers that follow you to other sites: we count visits with Cloudflare Web Analytics, which sets no cookies, stores nothing on your device and builds no profile of you. It is the only measurement on the site. Signing up stores your email so the account exists, that is the only thing kept that you did not choose to add.
Open the map once on signal, then save the layers you want before you leave, and the app keeps working with the phone in airplane mode. It is built for canyons. Only the very first load needs a connection.
The sources are public, and we name every one. What is not public is the work: cross-referencing them against each other, scoring the ground, and tracking which creeks are workable this month. Once you save spots, it ranks against those too.
Never. A marker is a public record, not permission. The app shows land status, claims and access notes precisely so you can check before you go, and it says so on every pin.
All fifty, plus DC, each with its own guide: gold, gems, legends, caves, fossil ground and live water data.
Yes. There are 133 countries on the map now, from the Klondike to Socotra, Ennedi to Antarctica, each with its own page and every entry carrying its source. Terrain relief is worldwide. The deepest data, mining claims, land ownership and river gauges, is still United States only.
No card, nothing to cancel.
