Tucson AZ

Tucson is the second largest city in Arizona. To no ones surprise, Phoenix about 90 miles to the north of Tucson is the largest. Tucson existed long before telephones let alone the 520 area code. Tucson is the oldest city in Arizona.

In fact, the city’s history began as long as 4,000 years before its incorporation in 1877. Native Americans farmed an area at the base of Sentinel Peak. The Peak, at over 2,900 feet, provided the Spanish a lookout point over the entire city when it was a part of New Spain.

Since 19Zz, Sentinel Peak is also know as “A” mountain. “A” mountain is an integral part of the history of the University of Arizona.
