Shattercone Faceplate from Glover Bluff, Wisconsin

Shatter Cone Museum Grade

Fine multiple "horsetail" shatter cones in yellow dolomite, on BOTH sides from a site where shatter cones are next to impossible to find. This IS a GREAT rarity, and will be a distinctive addition to any collection of impact materials.

7" Wide X 12" Long X almost 2" thick

A whopping 9 pounds! There will NEVER be another one like it. For the serious impact materials collector only.
