Gold Prospector App

Read the land. Strike gold. Gold Prospector is the all-in-one app for recreational gold prospectors and metal detectorists. Built by a lifelong prospector, it brings together AI, GIS mapping, 1-meter LiDAR, historic topos and more! — FEATURES — OFFLINE MAPS Download areas before you go and use them with no service, even in airplane mode. LiDAR, historic topo, roads and trails, claims, public lands, property lines, 3D terrain, and all the other layers come with it. Log finds and record tracks with no signal. 1-METER LIDAR HILLSHADE USGS 3DEP shading that reveals what the ground remembers: placer cuts, hydraulic pits, tailings, benches, and old water races, even under a century of brush. Ultra 1m covers California, Oregon, Idaho, Nevada, and Arizona, with more states coming. PAY STREAK ZONES Modeled gold-potential zones built from stream geochemistry, geology, and the density of historic workings, ranked within each region so the best ground stands out. HISTORIC MINES & RAILROADS Every recorded mine, prospect, and placer working nationwide, plus pre-1911 rail grades and the stops that served the camps. ROADS & TRAILS Every road and trail from USGS, the Forest Service, and BLM, with surface, vehicle class, seasonal closures, and who manages it. GOLD TRAPS Creek bends and steep gullies near known gold occurrences. The places moving water slows down and drops what it was carrying. STREAMS, RIVERS & LAKES Every waterway in the lower 48. Line weight follows actual flow, and the map tells you which run year-round and which only after rain. HISTORIC TOPO MAPS Scanned USGS topos from 1879 to 1940, overlaid on the modern world with an opacity slider. HISTORIC MAP BUILDER Over 350,000 town and city maps from the late 1800s through 1930, placed on the modern map. GHOST TOWNS 43,000+ abandoned towns, camps, and forts. Tap one to research its history. CLAIM WARNINGS The app watches your position and tells you when you step onto a mining claim or near one, whether the layer is on or not. COIN & RELIC ID Photograph a coin, button, buckle, or nail for an instant ID — type, mint years, material, and history. AI TERRAIN ANALYSIS Snap a photo of any creek or hillside and let the AI score its gold potential.
