Awesome freshwater high altitude dive. I did three dives, the last dive being a moon lit night dive. Water so clear the moon gave off reflected colors of red and greens. During the day you could see the tree's reflection at the surface. 1000 year old petrified forest cool lava formations. Not much life, saw a few fish, and green algae that grows around the craters and vents where the fresh water comes up from deep in the earth.
