"A Mountain" (Sentinel Peak)

"A Mountain" is a fixture in Tucson, AZ. Formally named "Sentinel Peak," it stands at 2,897 ft elevation and over looks Downtown Tucson and the I-10 freeway.

The "A" was created in the 1910's by UA students using local rock mined from the mountain itself... and during the week of the ASU-UA football game UA students guard it from being painted the colors of the rival school.
