Pan and zoom around the map and locations will pop in and out automatically based on the viewable map area. It is a little slow at the moment, please be patient as this is a work in progress.
There is a known issue where sometimes no locations are displayed between map levels 2 and 4. Things start running ok from zoom level 5 and onwards.
Disclaimer: Even though I am making this information readily available and try to ensure the information is as accurate as possible, before fossicking at a site you should do your own research to confirm if you can fossick in an area, and that that area contains the minerals for which you are looking. It is the individual fossicker's responsibility to gain permission before fossicking at any location.
