Shelley Senior High School is an institution for public education in the town of Shelley, Idaho. It is the city's only high school, and is nicknamed "the spud cellar" because of its unique mascot and resemblance to a potato cellar. The mascot, King Russet, is a Russet Burbank potato (the variety most commonly grown in the area) with a scepter and crown. The approximately 600 students, called Russets, receive two weeks of break in late September because some of them work in the local potato harvest.
