BombShard
Stone sculpture made from naturally sourced fragment of volcanic bomb shell, collected near Burns, Oregon. Base made from obsidian collected from nearby rhyolite flow.
Height 10", width 6".
This piece is made from a piece of the broken shell of a large volcanic bomb. The bomb originated as a blob of molten lava that was thrown into the air by a lava fountain, and cooled as it flew, contracting and cracking along the way. The core of the bomb was dense black lava with tiny white feldspar crystals. The base is made of banded obsidian from the Burns Butte Rhyolite flow. collected a few hundred yards away from the bomb fragment. Both eruptions occurred around the edge of a giant caldera, which was the source of the Prater Creek tuff, which covered hundreds of square miles with a thick layer of hot ash when it erupted.
