Mill Creek Drainage - Harvey Gap / Killer Green Thundereggs

These are sometimes called Harvey Gap, but the original finder decided to call them the Killer Green Eggs - sometimes abbreviated to the K.G.E. - which is how they are best known now. While not exactly rare, they are not common either and a great addition to the collection. They are also quite uniform in their characteristics - lots of quartz, usually grey agate in the signature green matrix. So when something else does show up, it is all the more striking. These extras include moss and tubes, occasional amethyst (very sought after) and once only in my experience what looks like green jasper! still quite a special item for a collection. And, for me, they are one of the high points of the mill creek area.
