A significant expansion of the Great Sand Dunes National Park was announced yesterday.   

The Nature Conservancy said they are working with the Department of the Interior to transfer just over 9,000 acres of land over to the National Park System to be included in the existing Great Sand Dunes National Park.   

Coming in at 750 feet tall with an estimated 5 billion cubic meters of sand, the Great Sand Dunes National Park and Preserve is home to the tallest sand dunes in North America.
