Colorado Intercollegiate Baseball Association

The short lived Colorado Intercollegiate Baseball Association or CIBA was formed as a declining number of Rocky Mountain Athletic Conference schools at the time were shutting down their baseball programs. From 1987-1991, the RMAC did not sponsor baseball in at least one year.

Although some timelines overlap with the RMAC, the CIBA was a baseball only conference with schools that were not yet in the RMAC. Charter members of the RMAC that participated in the CIBA were Colorado School of Mines & Colorado College.

Future RMAC members included University of Denver, Regis College, & Metropolitan State College.
