Intermountain Union relocated to the Billings Polytechnic campus after a series of earthquakes destroyed its Helena buildings in 1935.

IUC merged with BPI in 1947, when students named their own school to create today's Rocky Mountain College.

The college is a member of the National Association of Intercollegiate Athletics (NAIA), primarily competing in the Frontier Conference for most of its sports since the 1936–37 academic year; its skiing teams compete in the United States Collegiate Ski and Snowboard Association (USCSA).

Men's sports include football, basketball, cross country, football, golf, soccer, and track & field (indoor and outdoor); women's include basketball, cross country, golf, soccer, track & field (indoor and outdoor), and volleyball; and co-ed sports include cheerleading, ski racing and stunt.
