Bull Bison in Thermal Steam
$100.00 – $1,500.00
A bison bull was feeding along the edge of a runoff channel from Grand Geyser. He stood in the steam, brushing the snow from the grass, his head and body emerging occasionally as the heavy steam drifted and rose around him. There were a couple of advantages for him to be in this spot; the snow cover was much thinner because of the warm ground and the warm bath of steam made it easier for him to endure the winter cold.
