Last Friday for National Geologic Map Day, the USGS and AASG released a brand new version of the National Geologic Map Database. I spent hours on end exploring it when I first discovered the new version, and the excitement hasn’t even begun to fade. This afternoon I hosted a ~50 minute Google+ Hangout on Air (embedded below) where I, and a couple of other geologists, discussed the new website with the USGS’s product chief Dave Soller.
The database looks really great and even though the coverage is not yet complete, there is a lot there to explore, and a lot more in the pipes that should be released in the coming months. I’d encourage you to explore it for yourself – it may be the next best thing to getting out there in the field and seeing the geology in person.
