Analysis of information sources in references of the Wikipedia article "Garrison High School" in English language version.
The first school in Garrison, a log church-schoolhouse near Greenwood, burned in 1886. Classes were taught in private homes until the Mineral Springs Institute was built east of the railroad tracks in 1895. In 1911 a brick school was built on the site where later the elementary school was located. In 1916 this building was destroyed by fire.
