FINDING MINERALS
 

Ten sets of images are displayed at a time.  Browse the archives for past pics, or just keep hitting "Older" to load more pics. 

You may filter the view of the archive to find minerals in a certain geographic area, or those that respond to specific wavelengths or have other characteristics.  If the view is filtered the results show only that selection.

Famous localities are listed as separate geographic areas under Region View.

Using the search box above you may find specific minerals, mines, or localities.
