Sierra Grande
Largest extinct volcano in northeastern New Mexico, Sierra Grande rises to an elevation of 8,720 feet, one of many volcanoes, cinder cones, and flows that cover more than 1,000 square miles of area in northeastern New Mexico and southeastern Colorado eastward to the Oklahoma state line.
The state has a rich tradition of cowboy culture and rodeo, with many annual events celebrating this heritage. One of the most famous is the annual Albuquerque International Balloon Fiesta, which features hundreds of hot air balloons and draws thousands of visitors each year.
