Caves that are lava tubes generally aren't this colorful and this cave is no exception. Shooting in a cave is a new experience to me and basically I was pointing the camera into blackness and pushing the button. This ice waterfall shows some illumination on the bottom (somebody was shining a flashlight) and some of the red lava (or earth) above. The lavender is some sort of artifact of technique because I recall no colors like that in the cave - but it looks nice in the picture.
