History of Summit County

Summit County was created a long time ago, on November 1, 1861. It was one of the first 17 counties in Colorado. The county got its name because it has many high mountain summits.

When it was first formed, Summit County was much bigger. It included land that is now several other counties. These included Grand, Routt, Moffat, Garfield, Eagle, and Rio Blanco counties.

Over time, parts of Summit County were separated to form new counties. In 1874, Grand County was created from its northern part. Later, in 1883, Garfield and Eagle counties were also formed. After these changes, Summit County reached its current size and shape.

Geography of Summit County

Summit County covers about 619 square miles (1,603 square kilometers). Most of this area is land, with 11 square miles (28 square kilometers) being water. This water makes up about 1.8% of the county's total area.

The land in Summit County is very mountainous. The lowest point is about 7,957 feet (2,425 meters) above sea level at Green Mountain Reservoir. The highest point is Grays Peak, which reaches 14,270 feet (4,350 meters). Breckenridge, the county seat, is also very high at 9,602 feet (2,927 meters). This makes it one of the highest towns in Colorado and the United States.
