Product Description

Authentic TNT Cone Glover Bluff Meteorite Impact Site Original Cone
This is a TNT cone that we found at the Glover Bluff Impact Structure quarry, in 2002. We were there on expedition with Dr. Ray Anderson (who worked with Eugene Shoemaker on the Manson Structure). As if true asteroid impact shatter cones aren't weird enough -- we discovered this strange cone-shaped rock at a verified meteorite impact structure, yet this not a true impact shatter cone.

Made of dolomite; cone-shaped; and sporting a very odd flower-like design imprinted into the apex -- this specimen baffled impact scientists, geologists, and mining engineers all around the world.

Finally, a paper published in 1968 by Robert Deitz, the grandfather of impact science, solved the mystery. This is an example of a TNT CONE -- a pseudo-shatter cone -- formed during quarry operations several decades ago. The round apex was actually the bottom of a drill hole -- (the dynamite sticks would have been dropped down the hole, coming to rest on this surface at the bottom), and the flower design on top is actually the imprint of the final few strokes made by the reciprocating, star-shaped drill bit type (shown).

This full-size TNT CONE is the original. Very, very few are ever are found around the world as most get shattered to oblivion from the quarrying explosion. We found a total of six. We have never found any others at any other impact sites.

Location: Glover Bluff Quarry, Wisconsin, site of Glover Bluff Impact Structure.

Size: 6 3/4 L X 4" W X 2 3/4" D, Weight: 2lbs 1.7 ounces

If you have a geological collection, this would probably be one of the rarest specimens in your collection.
