Desert Pirate's Booty

There's lots of black obsidian there, although much of it is mixed with rhyolite and other igneous material. The yellow and reddish rocks below the black obsidian includes some rare pumpkin obsidian. A couple of the black pieces have traces of snowflake obsidian. We'll go back later for more of the flat sedimentary rock for landscaping in Idaho and Oregon.
