Amazing #winter shot of Great Sand Dunes #NationalPark and Preserve in #Colorado. David Paul Davie took captured this shot of dark clouds rolling over the park's main dunefield, which covers approximately 30 square miles. #GreatSandDunes is home to a diverse landscape of grasslands, wetlands, conifer and aspen forests, alpine lakes and tundra -- not to mention the tallest dunes in North America.
