Jewel Cave National Monument

When Jewel Cave National Monument was established in 1908, less than one mile of it was documented. Today, we know it's more than 180 miles long -- the third largest cave system in the world! Exploration continues to push the frontier, revealing rare formations and more contributions to science. There is much do discover both above and below ground. Jewel Cave National Monument is located in South Dakota.

About the Artist

Photographer and graphic artist Rob Decker studied photography with Ansel Adams in Yosemite National Park during the summer of 1979. The experience solidified his love of photography and our National Parks. Now he is on a journey to photograph and create iconic vintage-style WPA travel posters of all 62 major national parks as we celebrate the next 100 years of the National Park Service.

"I feel that it’s important to protect America’s special places, and to connect people with nature. And it’s up to all of us to pitch in. Perhaps more importantly, we need to inspire the next generation of park stewards. I’m trying to make a difference by giving back to the amazing organizations that support our National Parks. I donate 10% of annual profits, so when you buy one of these original works, you're helping these trusts, conservancies and associations, too."
