Mammoth Hot Springs Poster

This large complex of hot springs on a hill of travertine, is a key feature in Yellowstone National Park. The limestone deposits created over thousands of years form impressive steps over which geothermic waters continue to flow. Travertine comes in white, tan, cream-colored, and even rusty varieties -- depending on the mineral and algae deposits within them.  Our sturdy, acid-free paper is made from a blend of natural fibers and post-consumer recycled content, allowing you to make a big impact on your walls, but not on the environment. Quick Specs: FSC Certified  Made in the USA Museum-grade archival paper Fits standard frame
