Guston is an abandoned ghost town in Colorado that was settled in 1883 and named after the Guston-Robinson silver mine. The town experienced growth with the construction of a railroad and tollway, reaching a population of 300 by 1890. However, the town was abandoned in the late 1800s due to a drop in silver prices and most of the buildings had collapsed by 1950. You are still able to see some of the remains of Guston and the other mines in the area.
