I call it "Obsidian Motion"
Lens: Pentax DA 50-200mm WR Camera: K50 Photo Location: Hawaii Island 
Posted By: gildedfool, 11-27-2014, 10:07 PM

I usually think that the whole crashing wave shot motif is a bit played out, but I thought I'd share as I'm pretty pleased with how this one went. Especially given that I didn't mean to take this picture.

Obsidian is not really a mineral because as a glass it is not crystalline. It needs to have a crystalline structure to qualify for a mineral.
