Formation and Composition

The Kobuk River Sand Dunes were formed by the erosion of the surrounding permafrost and the transportation of sand by the wind. The sand is primarily composed of quartz, which gives the dunes their bright, white color. Over time, the wind has shaped the dunes into towering mounds, some reaching heights of over 200 feet.

Flora and Fauna

The dunes are home to a diverse range of plant and animal life, adapted to the harsh Arctic climate. The vegetation includes grasses, sedges, and forbs, which provide food and shelter for various animals. Some of the wildlife found in the area include the Arctic fox, snowy owl, and the elusive caribou. The dunes also serve as a critical habitat for migratory birds, making it an important area for birdwatchers.
