West Thumb Geyser Basin

Wintertime draws bison near the steaming hot pools for warmth and food. As they wander about this thermal area in the fog, their frosted ghostlike presence creates a haunting experience. With colorful hot pools, bubbling paint pots, and spewing lakeshore geysers, West Thumb Geyser Basin is con-stantly active.
