Sulphur crystals from the hottest regions of Nymph Creek, a thermal site within Yellowstone National Park. This is crystallized sulphur, the sulphur usually forming bipyramidal or rhomboidal crystals, and here they are fused to form a filament. The filaments can be quite long and are often the physical or metabolic substrate for various bacteria. Phase contrast photograph by Kathy Sheehan and David Patterson. Images were taken of samples from thermal sites in Yellowstone National Park at the Thermal Biology Institute of Montana State University, August 2001. Image copyright: D. J.
