For Nevada, this app is loaded with old workings to explore. As a geologist, it's perfect to gather location coordinates and names of the working for places I've never been or seen. The USGS links never work, however (perhaps they're just empty), and the ads are very obnoxious. Some Google Play credit can fix the ads, though.

with links to data reports and other details this app really gives you a deep look at past and present mining claims, at least the ones I have looked into in Oregon, California and Nevada, I love this app for searching out new prospecting locations so I know just where I want to go before I take my next trip and with gold continuing to sore it's a must have app for today's hobby miner!

Ads, not much else. all three location I click on I get an ad... then when trying to view info from USGS it fails. waste of my time.
