Sunset in Badlands National Park, South Dakota, United States

Layers of change. Badlands National Park, South Dakota, United States

Layered ridges stretch across Badlands National Park in South Dakota, United States. Their bands of pink, grey and gold shift with the light as eroded peaks and valleys come into view. Wind and water continue to shape this terrain, steadily wearing away soft sedimentary rock and exposing millions of years of Earth's history in layers formed by ancient rivers, volcanic ash and periods when shallow seas covered the region.

Beneath this rugged surface lies one of the world's richest fossil beds, preserving the remains of early mammals such as ancient horses and relatives of modern rhinoceroses that once roamed the region. The Badlands are only a window into the past. Today, bison graze the open prairie, bighorn sheep move along steep ridges and prairie dogs gather in active colonies across the grasslands.

Scenic roads and overlooks trace the contours of the land, offering sweeping views. Even now, layers of the past continue to emerge as the landscape slowly transforms.
