This vintage postcard features a vibrant image of the Oblong Geyser Crater, a notable geothermal feature located in Yellowstone National Park. The colorful mineral deposits and rising steam are beautifully captured in this early 20th-century photograph, printed with a textured halftone technique typical of postcards from that era. The postcard was published by Haynes, the official photographer of Yellowstone National Park, known for their high-quality and historically significant images of the park's natural wonders.

Measuring the standard 5.5 x 3.5 inches, this postcard presents not only a scenic view of one of Yellowstone's fascinating geyser craters but also a collectible piece of Americana. The back of the card is divided with space for a message and address, including postage rates of 1 cent domestic and 2 cents foreign, indicating an early 1900s production date. This postcard is ideal for collectors interested in national park memorabilia, vintage photography, or natural geothermal phenomena.
