View Original Image at Full Size

What looks like snow is actually an ash layer from a volcanic eruption that occurred about 1200 years ago at nearby Mt. Churchill. 1200 year old stumps were preserved in the ash layer and scientists could use these samples to extend living tree-ring records back in time. Photo Credit: Nicole Davi
