In 2003, I contacted the Mission Office asking about the boundaries of the mission. As a result, they sent me the map below showing the boundaries. I called the office again in 2009, and received an updated map that I cannot post. But it shows only very minor changes in the ATM boundaries--at least at the scale of this map--primarily in the area immediately west of Phoenix where the Buckeye Stake is now in another mission.

Also, here is a short, written discription: the mission covers a narrow slice of Arizona that runs for the central Arizona-New Mexico border to the southwest corner of the state. Some of the cities included are: Pie Town (NM), Show Low, Chandler, Tempe, Coolidge, Casa Grande, Gila Bend, Ajo, and Yuma.
Below is the contact information for the mission office. To write to a missionary currently serving in the mission, please send mail to him or her at this address.
The mission office telephone number is for mission office use only. Individual missionaries can not be contacted at this number.
