OF THE GREAT BASIN
The Great Basin of Western North America
lies between the Columbia River Basin to the north and the
Colorado River Basin to the south.
he Great Basin has no drainage outlet and is a vast desert interspersed with shrinking wetlands and mountain ranges. The mountains include sedimentary rock formations and have higher precipitation than the surrounding deserts and are home to a wide variety of flora.
The most well-known mountain ranges for alpine plants are the Ruby Mountains and the Snake Range (Great Basin National Park) in Nevada and Steens Mountain in Oregon.
