Before you head out

Stay out. Stay alive.

Never go in. Old shafts and adits hold bad air, rotten timbers and hidden drops. People die in them every year.
Watch the ground. Shafts hide under brush and boards. Stay on solid ground and keep well back from any opening.
Know whose land it is. Many sites are on private land or active claims. Turn on the Land owner layer and respect posted signs.
Locations are approximate. Records come from USGS maps and reports, some over a century old. A pin can be hundreds of feet off.

Mine Hole shows this briefing before the map opens, and marks every shaft and adit as a hazard. More from MSHA’s Stay Out–Stay Alive program.

Good to know. Site records are public-domain USGS data and can be dated or off by hundreds of feet. Many sites are on private land or active claims; a pin on the map is not permission to visit. Maps and overlays cover the United States and load over a connection unless you’ve downloaded the area. Mine Hole isn’t a navigation or survey tool.
