Cow by Belle Fourche River, Devil’s Tower, Wyoming

A lone cow grazes near the Belle Fourche River, with the distinctive red rock formations of Devil's Tower National Monument in the background. The Belle Fourche River, the longest river in South Dakota, flows through Wyoming and is a vital water source for the region's agriculture and wildlife. Devil's Tower, a laccolithic butte composed of igneous rock, was designated the first national monument in the United States in 1906. Cattle ranching has been a significant part of the economic and cultural landscape of this area for over a century, with the river providing essential grazing land.
