Gary Green Bog Agate / Larsonite / McDermitt Bog Agate

Gary Green Jasper, aslo known as Larsonite or McDermitt Bog Agate, is a beautiful greenish layered and swirled material formed when a swamp full of trees, cattails, algae and other material was buried by a volcanic event about 12 million years ago. The volcanic ash buried the swamp, compressing and preserving the petrified material. Elements from the volcanic ash infiltrated the swampy material and gave it the colors.
