Here is an interesting map that allows you to view and compare aerial photos of urban parts of maricopa and pinal counties over the years. It has aerial photography going back to the 1930's.
It takes some figuring out to figure out how to use it.
You can either view aerial photos for a specific year.
Or you can compare two different sets of photos for the same location.
On older photos, it superimposes the current streets on the old photos so you can figure out what you are looking at.
