Prospecting Log: Gold Story

The full Pro lesson course is here — read the water, master technique, know the rules, for US rivers. Log a find in fifteen seconds; the offline USGS map does the rest.

Gold Story is the prospector's field companion — offline USGS gold-site maps, a fifteen-second find logger, and records that turn your seasons on the water into a story worth telling.

THE MAP KNOWS WHERE TO LOOK Historic USGS MRDS gold occurrences, prospects, and past producers — the same records the pros research — rendered on a fast offline map. Install a region pack once and the whole area works with no signal, deep in the canyon where gold lives. Tap any site for its record and commodity notes. The map is honest, too: these are historic sites, not current claims, and the app reminds you to verify land access before you dig. The basemap now follows your appearance — a warm daylight palette in light mode, a night-jungle ground after dark.

REGION PACKS, FULLY OFFLINE The California Mother Lode is built in; more US gold regions — Nevada now, others on the way — download in a tap with Pro. Each pack covers a storied region and works completely offline once installed.

BUILT FOR US GOLD COUNTRY Gold Story's maps, gold-site data, and legal guidance are United States-based. The technique and geology lessons apply to rivers anywhere, and your journal, spots, and find logging work worldwide. Storage sizes are shown up front; remove and reinstall any time.

LOG A FIND IN FIFTEEN SECONDS Weight, method — pan, sluice, highbank, dredge, detector, sniping — water and conditions, done. Your location attaches automatically. Add a photo if the color deserves it, then get back on the gold.

NAME YOUR SPOTS Mark the lower riffle, the inside bend, the bedrock crack that keeps paying. Finds within 150 meters attach to their spot automatically, so your journal reads like a map of your own river knowledge. Spots are private, on your device.

RECORDS WITH A GOLD SHIMMER Your best find gets a quiet celebration and a permanent marker in the journal. Past trips keep their duration, find count, and total weight. Stats show finds by method, weight over time, and which spot earns its reputation.

AI THAT READS YOUR RIVER NOTES Scribble "small picker, sniping the bedrock crack, water low and clear" and on-device AI fills the method, water, and conditions fields for you. After a trip, it writes a recap from your own numbers — nothing invented, nothing leaving your phone. Three free uses a month; Pro removes the cap.

LESSONS WORTH READING Reading the water, where gold settles, technique by method, and the legal side of prospecting in the US — a full course in plain language, honest about what's been reviewed by whom. The complete course is part of Gold Story Pro, and the technique and geology lessons apply to rivers anywhere.
