Volcanic Bomb (EB12)
Notes specific to this specimen: Large, rare, combination fusiform bomb. This is the result of three individual magma projectiles running into each other in flight. In this case the merge of these three individuals was early in the ejection event but after the individual projectiles had started acquiring their own individual character. The combination of these three bombs resulted in one very large cigar-shaped bomb which acquired it’s own form which dominated the final shape before falling back to Earth.

Volcanic Bomb (EB14)
Notes specific to this specimen: Rare double bomb. These unique specimens form when two magma projectiles run into each other in flight before they completely harden. In this case the merge was early in the ejection event, before the two projectiles had started to acquire their own individual character. Instead the combination of the two was almost obliterated by the overall form taking shape before they fell back to Earth.

Volcanic Bomb (EB2)
Notes specific to this specimen: Rare, beautifully-shaped double bomb. These unique specimens form when two magma projectiles run into each other in flight before they completely harden. Each had started to acquire it’s own individual character before they combined and fell to Earth.

Volcanic Bomb (EB4)
Notes specific to this specimen: Large classic plump fusiform bomb with great aerodynamic striations. It looks like it encountered another in flight but did not complete the merging with it. Natural breaks reveals chalcedony interior which fluoresces a vibrant green. A great specimen.
