Great Sand Dunes National Park Postcard - Dune Photo
Postcards are affordable ways to commemorate your travels to national parks and share those adventures with friends and family. You can send them, keep them for yourself, or even send them to yourself! This postcard representing Great Sand Dunes National Park features a photo of a section of the dunefield featuring formations known as "Chinese Walls." These structures form at the top of reversing dunes, created when prevailing winds are subdued and storm winds blow from the opposite direction, creating the peaked ridge top depicted in the photo.
