One would think this area should be in Geyser Country; but, the lake in the background is Yellowstone, the centerpiece of Lake Country. All sections of the park have volcanic activity. The Yellowstone caldera boundry covers parts of Geyser and Lake Country. West Thumb jabs into the west side of the lake. I photographed the area late in the day with the sun at a low angle. Earlier in the day, sunlight glare on the hydrothermal features would have obscurred details. Photos are scanned 35mm slides.
