The glow on this map is our Gold Favorability Model — machine learning trained on 300,000+ federal mineral records and the geology, wall-to-wall across the West. Every known occurrence, claim, creek and rock unit underneath it. We don't sell the data. We sell the read.

Gold leaves a trail. The data to read it is public — it's just unreadable.
Lode gold sits in the rock up high. We map the known occurrences and the geology that hosts them, so you can see the sources above you.
Gold weathers out and rides the creeks downhill. Click a source and the drainage below it lights up — the water that carries placer down to where you can pan it.
We overlay active mining claims so you can see what's already taken — and we tell you, plainly, to verify the legal status before you ever dig.
Machine learning, pointed at one question: where should gold be?
We trained a model on 300,000+ federal gold records and the geology of the West — the host rock, the faults and quartz-vein country gold rides, the terrain that moved it. The glow is the answer: the brighter the ground, the more it looks like ground that has produced gold. And members can click ANY spot for the read of that exact ground — the model's take, the creeks that drain it, the rock story, who owns it.
Eleven states wall-to-wall. Cold ground is honestly cold — the empty stretches are real.
Gold dots mark where it was found. The glow says where the ground looks right — around them and beyond them.
Flip to bare-earth LiDAR and the heat rides along — the old-timers' diggings show right through the forest.
Everything on the map, named.
No guessing what's inside. Here is the whole stack — every base and every layer, and membership opens all of it at every zoom:
USGS topo · satellite · NAIP hi-res closeups · bare-earth LiDAR
266,000+ recorded occurrences and producers, color-coded, with a gold-only filter · the Gold Favorability heat · the geologic map
Prospect pits and trenches · adits · mine shafts · mines and open-pit mines · mine dumps and tailings piles — each kind with its own marker; dredge and placer tailings mark proven placer ground
Live BLM mining claims, placer and lode · land ownership — public-land tint, private-land hatch
Every USGS stream — click a gold source and the drainage below it lights up · roads down to the Forest Service numbers
2D · full 3D terrain · offline trip packs with GPS in the field
All of it at once, in 3D: the Bohemia district on satellite — the heat glowing on the high ground, gold dots, adits and shafts, claim lines, streams, the roads in, and a member's pin on the spot he's working up.
Pick your ground, read it, plan the day.
Headed somewhere? Pull up the ground first. The gold dots are every recorded occurrence around it.
Turn on the favorability. Where does the model run hot around the dots — and beyond them? The one-minute walk-through →
Bare-earth LiDAR strips the forest off. Old pits, trenches and tailings are still sitting there.
Streams and roads: pick the creek that drains the hot ground, and see how you'd actually get there.
Or click the spot and let the spot report do all four for you — the verdict, the rock story, and a day plan for that exact ground.
