The building used to house Rocky Mt. High School was completed in 1956 to house the Byron High School. At that time only student from Byron attended the school. A typical graduating class from Byron High School had about 20 - 25 students. In 1983 it was decided to consolidate the three high schools in the north end of Big Horn County into one school. The three schools were Byron High School, Cowley High School, and Deaver High School.
