"The Basin and Range region is the product of geological forces stretching the earth's crust, creating many north-south trending mountain ranges. These ranges are separated by flat valleys or basins. These hundreds of ranges make Nevada the most mountainous state in the country."
National Park Service"Nevada is the most mountainous U.S. State, with over 150 (named) individual mountain ranges; major ones include the Battle, Monitor, Ruby, Santa Rosa, Schell Creek, Sierra Nevada, Snake and Toiyabe. Over 30 of Nevada's mountain peaks exceed 11,000 ft., with the highest point (Boundary Peak), reaching 13,140 ft."
