About this postcard

The picture shows Sponge Geyser in Yellowstone National Park, a low, reddish mineral cone with steam rising against a forested hillside and a pool of water at its base. The printed caption names it Sponge Geyser, and the card was copyrighted by Haynes Inc. of Yellowstone Park, Wyoming. Sponge Geyser is a small geyser in the Upper Geyser Basin, and its surrounding sinter terraces and runoff channels are colored by mineral deposits and thermophilic organisms.
