Monument Valley draws tourists from around the world for its tours of the magnificent rock formations, but what brings the locals is the well at the Seventh Day Adventist mission. The well is a rarity, a reliable and clean source of water, clean enough that haulers will pass by other wells and make longer trips to fill up. Lines form early each day, including the Elvis Saltwater and his children, Fidel and Javier, who wait for their 425-gallon tank to fill.
