Loosely related, but I was thinking about how Facebook has a treasure trove of information with regard to backcountry data such as waterfalls and sensitive rock art sites. Many people in my area post photos of these sites to Instagram without a location tagged, but they likely upload with the actual location data still in the image metadata. Because of this you could put together some pretty comprehensive glimpses at these hotspots.
