Caption: A cross section of a quartz crystal obtained from rocks near Yellowstone. Crystals of quartz and zircon harbor geochemical clues to past -- and future -- volcanic eruptions in the Yellowstone caldera. In the past, eruptions over this "hot spot" in the Earth have been of a magnitude that would have severely altered Earth's climate.
