USGS Arizona coverage

We’ve expanded our coverage of USGS 7.5 minute 1:24000 scale maps with the additional of approximately 100 “new” topographic maps of Arizona.  These historic maps date from the 1950s when Route 66 was alive and well through the 1980s when the interstates had replaced the mother road.  We also have coverage in areas such as southern Arizona where an explosion of growth has taken place.

We’ll have more to come as we continue to can approximately 100-200 maps a week.
