In January 1915, the residents of Calneva, a Western Pacific Railroad station in eastern Honey Lake Valley desired the break away from the Fairview School District and form their own. In their petition, they stated nineteen scholars resided in the proposed district. Their request was granted on February 2, 1915 by the Lassen County Board of Supervisors. The new district was named Fort Sage. The school was located in a small one-room building on the Harry Hill homestead. It was later moved to the Aldrich House, a larger building, located in the center of the district. In the summer of 1918, the school was on the verge of being suspended, as enrollment declined to four. The trustees persuaded County Superintendent of Schools, Julia A. Norwood, to keep the school open, as they promised an additional four students would attend in September. The request was granted. The school’s existence was brief and it was closed in 1924. In 1926, the furniture from the school was purchased by the Janesville School District.
