Coulee

A coulee is a term primarily used in North America, particularly in the Western and Midwestern regions of the United States and Canada, to describe a valley or ravine formed by glacial meltwater or erosion. It often features steep, exposed rock faces, and can vary in size from small gullies to significant canyons. The term can also refer to a dry stream bed, a shallow depression, or a low-lying area. Coulees frequently act as drainage pathways and can harbor unique microclimates and ecosystems due to their varied topography and protection from the wind.

Coulee meaning with examples

• Hiking through the coulee revealed layers of sedimentary rock, carved by centuries of erosion. We marveled at the patterns the water had made in the canyon walls. The arid landscape, with its sparse vegetation, made the coulee a striking contrast.
• The farmer's field bordered the coulee, a natural drainage route that sometimes flooded during heavy rains. He was careful to plant crops that could withstand potential overflow to the benefit of the coulee's ecosystem.
• During the summer heat, the sheltered coulee offered a respite from the sun, creating a localized microclimate. The cool, shaded area was a great attraction to the many different types of animals.
• The ancient petroglyphs, etched into the rock face of the coulee, told of the area's history, with the stories that held many interesting facts. These carvings serve as a window into the area's distant past, preserving a cultural heritage.
• Following the coulee's path led us to a hidden spring, a source of fresh water in the otherwise dry landscape. The spring was a focal point for the local wildlife. It offered great food, rest, and relief from the heat of the sun.
