On a blue shield shaped embroidered device convexed at the top, edged with a 1/8 inch (.32 cm) black border, a Mustang rearing up to sinister. Attached above the shield, a silver scroll inscribed "SINAGUA" in blue letters 5/16 inch (.79 cm) in height above the San Francisco Peaks. The overall dimensions are 3 1/2 inches (8.89 cm) in height and 2 3/4 inches (6.99 cm) in width.
Blue and silver gray are the school colors. The Mustang, the school mascot, represents keen vision, strength, and precision. The stylized peaks, on the scroll, symbolize the San Francisco Peaks, one of the highest landmarks in Arizona, and sacred to local Native Americans.
