Distribution Comments:
Sierra Fresnal - East Obsidian occurred in the east coalesced rhyolite dome near Sierra Fresnal.  Marekanites have not been found in-situ at the dome, but below the dome eroding eastward towards Lago Fresnal and Lago Guzman.  Sierra Fresnal East has greater concentrations than Sierra Fresnal West.  Sierra Fresnal West and Sierra Fresnal East have different geochemical signatures.
