Product Description

Authentic TNT Cone Geological Specimen Original

Geological Oddity and Museum Piece.

As if true asteroid impact shatter cones aren't weird enough -- we discovered this strange cone-shaped rock at a VERIFIED meteorite impact crater site, yet it is 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.

This full-size TNT CONE is the original. Very, very few are ever found, and therefore even in existence. Most get shattered to oblivion.

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