It is the oldest of the three traditional high schools of the Pocatello/Chubbuck School District and serves the southwest portion. The school colors are red and blue and the mascot was an "Indian"; the city's namesake, Chief Pocatello, was the leader of the Shoshone people. The mascot was changed to the Thunder in June 2021 due to insensitivity.
