History
In the mid-1860s, coal was discovered in southwestern corner of Weld County in the Territory of Colorado. Erie was originally settled in 1867 and named after Erie, Pennsylvania, the former home of early settler Richard Van Valkenburg. In 1870, railway service was established by the Denver-Pacific Spur Railroad, and in 1871, the Denver & Boulder Valley Railroad was built through the area, connecting Boulder and Brighton. and the Town of Erie was incorporated on November 16, 1874. The first school was established in 1874, with 33 students enrolling.

Bell; called the Erie-Canfield Independent, it continued publishing until 1896. The Erie Herald was established in 1907 and published for far longer than other short lived newspapers, serving the community until 1948.
