and Boulder Creek, so named because of the abundance of boulders in the creek which hampered early gold prospecting efforts. Boulder County retains essentially the same borders as in 1861, although a of its southeastern corner and its approximate population of 40,000 became part of the City and County of Broomfield in 2001. Before the arrival of the first US settlers, the area was occupied by Native Americans led by
Chief Niwot Chief Niwot ( Hinóno'eitíít/Arapaho: Nowoo3 ɔ'wɔːθ or Left Hand(-ed) (c. 1825–1864) was a Southern Arapaho chief, diplomat, and interpreter who negotiated for peace between white settlers and the Cheyenne and Arapaho tribes during the P ...
on the plains and seasonally by Utes in the mountains to the west. The first European American settlers were gold prospectors led by Captain Thomas Aikins. His group of about twenty settled at the mouth of Boulder Creek Canyon on October 17, 1858. Chief Niwot told them not to stay and it is said they promised to move into the mountains to prospect in the spring. However in February 1859, they founded the town of Boulder. At about the same time, they also founded the first Gold Mining town in what would become Colorado,

which is about 10 miles west from Boulder. Gold Hill was founded because of the placer gold discovered there. The area was the site of the first commercial scale placer mine in Colorado, producing over 5,500 ounces of gold in the first year of operations (1859).

Over 13,000 people in Superior and 21,000 in Louisville were ultimately evacuated while the fire was spreading due to unusual 100 mile per hour winds. Additionally, one person died and another is missing and presumed dead. The cause of the fire has not been officially announced, pending an investigation. However, an incident report filed by a ranger with Boulder Open Space and Mountain Parks identified two ignition points for the fire. The first ignition point was a shed that began to burn at approximately 11:30AM MST, December 30, 2021. The second ignition point was upwind from the first, and started around noon of the same day on "western side of the Marshall Mesa trailhead".

Government

Boulder County is divided into three districts each represented by a commissioner elected county-wide. The three commissioners comprise the county Board of Commissioners and represent the county as a whole. Each commissioner must reside in their respective district and may be elected to a maximum of two four-year terms. The Board of County Commissioners are full-time public servants and approve the budget for the entire County government. The Board also oversees the management of 10 County departments and the daily operations of the county, work that is done by a county manager or a chief administrative officer in some counties. Boulder County has seven other county-wide elected officials, including the District Attorney, who represents the 20th Judicial District.

Since the 1990s, it has become one of the most liberal counties in Colorado; in most years, it is the second-strongest Democratic bastion in the state, behind only the City and County of Denver.
