1550. Frost Family. George Frost home. In the late 1880s George Frost arrived from the East in the Lake George area. After trying and failing as a rancher, he sold some stock and built a dam on the South Platte River. The reservoir became known as George’s lake and had an ice cutting business. His home was built on the side of the lake and, after his death in 1906, it became a hotel. It burned in 1922. Source: South Park Historical Foundation 2004.
