The Wind Cave National Park Poster is an original work created, numbered, signed and dated by the artist. The original photograph was taken by Robert Decker. The poster is created in the style of the Works Progress Administration (WPA), when the Federal Government — in the 1930s and 1940s — commissioned hundreds of artists to create thousands of poster designs for public exhibits, community activities, theatrical productions, health, safety and educational programs, nature and travel. By the end of the WPA era, only 26 National Parks had been established and only 14 parks had posters created for them.
Photographer and graphic artist, Rob Decker, studied photography with Ansel Adams in the summer of 1979 in Yosemite National Park, an experience that solidified his love of photography and our National Parks. Now he is on a journey to photograph and create iconic WPA-style posters of all 59 major national parks in time for the 100th anniversary of the National Park Service in 2016.

About Wind Cave and the Wind Cave National Park Poster
Wind Cave National Park is one of the oldest parks in the National Park system, and was established on January 9th, 1903. It was the first park created to protect a cave anywhere in the world. The Wind Cave National Park poster features the boxwork formations in the cave, as well as the ecosystem of the prairie.
Known for its displays of the calcite formation called boxwork, some 95 percent of the world’s discovered boxwork formations are found in Wind Cave. Considered a three-dimensional maze cave, it is recognized as the densest — most passage volume per cubic mile — cave system in the world. The cave is currently the sixth-longest in the world with 140.47 miles (226.06 km) of explored cave passageways, with an average of four new miles of cave being discovered each year. Above ground, the park includes rolling hills, pine forests and the largest remaining natural mixed-grass prairie in the United States.
The Lakota, Cheyenne, and other Native American tribes had known about the opening to Wind Cave and the winds that move in and out of it for centuries. The indigenous people who lived in the Black Hills region of South Dakota, spoke of a hole that blew air, a place they consider sacred as the site where they first emerged from the underworld.
Typically, air continually moves into or out of a cave, equalizing the atmospheric pressure of the cave and the outside air. When the air pressure is higher outside the cave than in it, air flows into the cave, raising cave’s pressure to match the outside pressure. When the air pressure inside the cave is higher than outside it, air flows out of it, lowering the air pressure within the cave. Wind Cave, with only a few small openings “breathes” more obviously than a small cave with many large openings. Rapid weather changes, accompanied by rapid barometric changes, are a feature of Western South Dakota weather.
Wind Cave National Park protects a diverse ecosystem with eastern and western plant and animal species. Some of the more notable animals include elk, bison, black-footed ferrets, pronghorn and prairie dogs. The Wind Cave bison herd is one of only four free-roaming and genetically pure herds on public lands in North America. The other three herds are the Yellowstone Park bison herd, the Henry Mountains bison herd in Utah and on Elk Island in Alberta, Canada.
