Step 1 : Introduction to the question "What is the biggest desert in the United States?"
...The Great Basin Desert, spanning about 190,000 square miles, is the largest desert in the United States and one of North America's four major deserts. Unlike the hot deserts of the Southwest, it is a cold desert characterized by high elevation and a climate defined by long, snowy winters and dry, hot summers. Primarily located in Nevada and extending into Utah, Oregon, Idaho, and California, the Great Basin Desert boasts unique ecosystems dominated by sagebrush and scattered juniper trees, and a variety of plant and animal species adapted to its harsh environment.
