The map above is from a National Geographic map of Mexico.
  

Many more maps are available now!

Unlike the early years, road maps and satellite photos are now available online. Below are some items courtesy of MapQuest.

The map above shows a rather zoomed-out look of of the area between El Paso and Constitución (look for the city labeled Benito Juarez, at just about the center of the map); to its right is the same area by satellite photo. Nuevo Casas Grandes has a church started by a man who was saved out of the church in Constitución.
  

The map above shows a much closer highway and city map, to its right is the same area by satellite photo. Constitución is the green area just south of the center.
 

Above is a collage I put together of several sections of satellite photos. In the past trips, we have gone climbing in the mountains to the south and east of Constitución. Ultimately, this proved that I am not cut out for mountain climbing. (I’ll share those stories elsewhere.)
