Colorful runoff from springs in the Upper Geyser basin. The Firehole River is in the foreground.
Beehive geyser in the morning light. Beehive is unpredictable, but usually erupts at least once a day, and can shoot more than 180 feet high. The steam plume in the background is Old Faithful geyser.
Lion geyser eruption. Lion is unpredictable, but usually goes in a series of 3 events about an hour apart. I waited about 45 minutes for this one. Luckily the sun was in the right spot to give a rainbow in the geyser steam!
