Due to the wide valley and open space, the Lower Blue River Valley, now the North of Silverthorne, was home to many flourishing homesteaders and ranches. Slate Creek, which sat at the base of Ute Peak, between Silverthorne and Heeney, was a small ranchers town with a schoolhouse and community center.

The Lower Blue River Valley was home to many homesteads. Some of these homesteads were very successful, including the Knorr Ranch, which at one point grew to 11,000 acres and was moved when the Green Mountain Reservoir was built in 1938. The original homesteader, William Guyselamn, sold the ranch to his daughter Corinne and his son-in-law William (Billy) Knorr. The ranch stayed in the family for generations.

What is a Homestead?
The Homestead Act of 1862 was signed into law by President Abraham Lincoln on May 20, 1862. The act defined how federal land could be distributed. Federal land was divided into 160 acres (approximately), and land offices were established for individuals. Men and women who were heads of household, over the age of 21 could apply for a petition. They had to develop the land, build a house, and live on the land for 5 years. When requirements were met, or “proved up”, they received a patent that granted them official ownership.
