About Us

Union Mine High School is a small Division 4 school located in the foothills of El Dorado County.  We compete in the Sierra Valley conference and are part of the Sac-Joaquin section.  We have a unique 4x4 schedule where all students take only 4 classes per half year and another 4 classes the other half the year. We offer most competive sports in the section and compete every year for our share of league titles.  The 2014-15 year saw the Diamondbacks finish second in the SVC ALL-Sports competition.
