T he snow capped Sangre de Cristo Mountains form a formidable barrier between the eastern United States and what is now New Mexico, Arizona, and California. But Americans moving westward during the early 19th century could not be stopped. At Raton Pass, on the border between Colorado and New Mexico, they found one way through the mountains, but it was narrow and steep, suitable at first only for pack horses. The broader, easier crossing at Glorieta Pass, between the mountains and the red wall of Glorieta Mesa, was another.
These two passes played critical roles in the events that ensured that New Mexico and the Southwest would become, and continue to be, part of the United States. In the 1820s, the first of many traders crossed the mountains on the Santa Fe Trail, hoping to make a fortune selling manufactured goods in the small city of Santa Fe or further south in the city of Chihuahua. In 1846 soldiers followed in the tracks of the traders. Dressed in uniforms of the United States army, they came down through Raton and Glorieta passes to claim the territory of New Mexico for a rapidly expanding American nation. Almost 20 years later, other men tried to take over the Southwest. The country they fought for this time was the Confederate States of America. Their defeat at the small but decisive Battle of Glorieta Pass ensured that New Mexico, Arizona, and California would stay in the Union.
