The Great Basin is an area of low precipitation, characterized by dry conditions and limited rainfall.

The Great Basin experiences low precipitation, making it an arid region with dry conditions year-round. Surrounded by mountain ranges that block moisture, the Great Basin is in a rain shadow, preventing significant rainfall from reaching the area. This results in desert-like landscapes, including salt flats, sagebrush, and dry valleys. Snowmelt from nearby mountains provides some water, but overall, the Great Basin receives minimal rainfall, which is a key factor shaping the region's ecosystems, vegetation, and wildlife. This low precipitation defines the area's climate and natural environment.
