The Great Sand Dunes in Colorado are a natural marvel, attracting visitors with their towering dunes and unique landscapes. While many people wonder about the discovery of these dunes, it’s essential to understand that they were known to Indigenous peoples long before European explorers arrived. The first documented European encounter with the Great Sand Dunes was by Spanish explorers in the 17th century. These explorers were part of expeditions searching for routes and resources in the American Southwest.
Who First Documented the Great Sand Dunes?
The Spanish explorers were the first Europeans to document the Great Sand Dunes. In the late 1600s, they traveled through the region, guided by Indigenous knowledge. The area was already well-known to Native American tribes, such as the Ute and Apache, who had lived in and around the San Luis Valley for centuries. These tribes used the dunes for spiritual purposes and as a landmark within their vast territories.
