For centuries people have passed through here as they move from the Great Plains to the high mountains.  The area is now known as Glorieta Pass but long before that name it was watched over by the peoples of the Pecos Pueblo followed by traders who settled what is now Pecos, New Mexico.  The ruins of the Pueblo at Pecos recall a huge village perched atop a perfectly situated mesa positioned squarely in the path of all who approached.  It was defensible and perfect for trade from both sides.  The Spanish came through in the quest for riches and the drive to expand their empire.  Other tribes came through and traded but also raided the Pecos Pueblo.  Eventually location was the downfall of the Pueblo and the last residents departed, the huge adobe and stone structure began its return to nature.  The ruins are protected within the Pecos National Historic Park.
