S mountain

On February 27, 1931, President Hardy permitted 500 students to paint rocks and form a 400-foot (120 m) "S" on Cowles Mountain. Nicknamed "S" mountain, the idea was created by the Council of Twelve and initially supported by Hardy. The giant S was lit at night for the opening football game of a season (performed by the freshman to build school spirit) along with pep rallies, and was repainted throughout its history. At the time, it was the largest collegiate symbol in the world.During World War II, the S was camouflaged to prevent it becoming a reference point for enemy bombing aircraft.It was returned to its normal state in April 1944. In the 1970s students stopped painting it and brush obstructed the symbol. After a 1988 brush fire it was exposed, and students repainted it. In fall, 1997, a group of 100 volunteers climbed Cowles Mountain after dusk to commemorate the one hundredth anniversary of the school by using flashlights to once again outline the "S" on the side of the mountain. In 1990, a high school prank defaced the S to read as "91" in honor of their graduating class.

School colors and mascot

The initial colors of the school were white and gold. When the junior college was added to the campus in 1921, its colors of blue and gold were merged, resulting in a blue, gold, and white color scheme. New colors were later chosen as gold and purple, until being replaced by crimson and black on January 28, 1928.

The school's prior nicknames for its mascot included "Normalites", "Professors", and "Wampus Cats". However, after a 1924 committee met to address the issue, the name "Aztecs" was decided on.In 2003, the Aztec Warrior was approved by a student and alumni vote to become the official university mascot after the school's prior mascot, Monty Montezuma, was discontinued.
