Obsidian Needles


My route went up to Davis Creek again this past Tuesday. I had a delivery at the local store/Post office combination and spoke to the clerk about some boxes of strange looking 'stuff'. The stuff turned out to be "Obsidian needles" which are 'mined' or dug nearby.


Obsidian is a rock that forms when certain types of lava cool very quickly above ground. It is an actual glass, only formed naturally. Obsidian is not uncommon, but the lava flow that produced these needles was very pure and made glass of an exceptional quality. Obsidian Needles are rare. They are naturally formed from the Obsidian bedrock under poorly understood conditions, an interlocking mass of broken needles, boulders, and a few intact needles.

The needle in this image is almost actual size (before it is enlarged - click image to view a larger picture with more detail)
