TheTown of Silverthorne is ahome rule municipality inSummit County,Colorado. According to the2020 Census, the population of the city is 4,402.[5]
The town was named for Judge Marshall Silverthorn who served as the judge of theminers' court inBreckenridge. The judge first came to town as a prospector and claimed a section of the Blue River in 1881. After patenting his claim in April 1882, he was disappointed to find the gold to be sparse and the claim a poor bet. The land passed to his daughters on his death in 1887 and was then sold several times to various mining companies. In 1953 Clayton Hill bought the property and subdivided it for homes and stores.[7]
Silverthorne served as a makeshift camp for workers during the construction of theDillon Reservoir from 1961 to 1963, and later as a stop alongInterstate 70. It was eventually incorporated on April 5, 1967.[2]
The city has expanded several times since incorporation by annexation.
Since 2016, the town of Silverthorne has hosted the Silverthon Games, an annual competition featuring a seasonally-based slate of individual and team events, culminating with the heavily spectated Hummingbird Circle race.[8]
