If you are on the west side of Tucson, our "A"mountain is quite obvious. Most of the year it is red, white and blue. It was constructed by the Univ of Az in 1915. It is actually on Sentinel Peak, which was a lookout for the indians and spaniards over the years. We had a lovely hike up there and want to share the following pictures. It is about 2900' high. Enjoy and God bless you!
