What Basin between the rocky mountains and the Sierra Nevada range?

The basin located between the Rocky Mountains and the Sierra Nevada range is known as the Great Basin. It is a large, arid region that encompasses parts of several states, including Nevada, Utah, and portions of California, Oregon, and Idaho. Characterized by its desert landscapes, the Great Basin is defined by its internal drainage system, where rivers and streams do not flow to the ocean but instead end in lakes or evaporate. The region is also home to unique ecosystems and a variety of wildlife.
