Muggins Mountain agate is found as thundereggs around Welton, Arizona near the Yuma Military Proving Ground. The dark colored “eggs” contains a rather small narrow agate core containing fluffy brown, yellow, and green moss-like plume inclusions.  This material rivals the infamous beautiful Priday Plume noted for its' floral bouquets.
