The old ones were here when the erupting earth spewed forth a fire river. They saw the red and orange molten rock fill the valley and saw huge plumes of smoke. They stared at the changing landscape for too long and the red burned into their eyes. So now we all have red eyes to remind us of a time that passed but may come again.
This is my take on a Native American tale I heard not long ago. After being in Lava Beds NP for two weeks walking over all that cooled lava flow I could not help but think of this common bird with its red eye.
