Chaffee County has a confusing origin. Between February 8 and 10, 1879, Carbonate County was created by the Colorado legislature out of northern Lake County. On February 10 the two counties were renamed, with the southern part of Lake County becoming Chaffee County, and Carbonate County becoming Lake County. Chaffee County is known as the “Heart of the Rockies”. It was named for Jerome B. Chaffee,[4] Colorado's first United States Senator.
