Boulder is located at the base of the foothills of the Rocky Mountains, at an elevation of 5,430 feet (1,655 m) above sea level.[11][12] The city is 25 miles (40 km) northwest of the Colorado state capital of Denver. Boulder is a college town, hosting the University of Colorado Boulder, the flagship and largest campus of the University of Colorado system as well as numerous research institutes. Starting in 2027, Boulder will become the new home of the Sundance Film Festival.

## History

[edit]

For a chronological guide, see Timeline of Boulder, Colorado.

Archaeological evidence shows that Boulder Valley has been continuously inhabited by Native American tribes for over 13,000 years, beginning in the late Pleistocene era. Throughout the Paleo-Indian, Archaic, and Late Prehistoric periods, indigenous peoples moved seasonally between the mountains and plains, taking shelter in winter along the Front Range trough where Boulder now lies. By the 1500s, the area was occupied by Ute tribes, joined by Arapaho tribes in the early 1800s.[13]

The Indigenous Nations who have ties to the Boulder Valley include the Apache, Arapaho, Cheyenne, Comanche, Kiowa, Pawnee, Shoshone, Sioux, and Ute peoples. In the 1800s, Euro-American settlers colonized the area.[14]

Boulder was founded in late 1858 when prospectors led by Thomas Aikins arrived at Boulder Canyon during the Colorado Gold Rush. Arapaho leader Niwot allowed them to stay for the winter, but the settlers abused this peaceful approach, and some later took part in the Sand Creek massacre of Arapaho.[15] In early 1859, gold was discovered along Boulder Creek, drawing more miners and merchants to the area. The Boulder City Town Company was formed in February 1859 to establish a settlement at the canyon mouth. The Boulder, Nebraska Territory, post office opened on April 22, 1859.[16]

On August 24, 1859, voters of the Pike's Peak mining region approved the formation of the Provisional Government of the Territory of Jefferson,[17] and on November 28, 1859, the extralegal Jefferson Territory created Jackson County with Boulder City as its seat.[18] By 1860, Boulder City had 70 cabins, occupied mainly by Anglo families. Non-whites like Chinese miners and black residents were part of early Boulder, but were rarely pictured.[13]

The free Territory of Colorado was organized on February 28, 1861,[19] and Boulder County was created on November 1, 1861, with Boulder City as its seat The Arapaho were forced to relocate by the Treaty of Fort Wise. With declining numbers, Niwot's band soon moved to the Cheyenne-Arapaho Reservation. By 1862, the creek had yielded $100,000 in gold, and Boulder's population exceeded 300.

On November 7, 1861, the Colorado General Assembly passed legislation to locate the University of Colorado in Boulder.[20] The City of Boulder City was incorporated on November 4, 1871.[4] On September 20, 1875, the first cornerstone was laid for the first building (Old Main) on the CU campus. Colorado became a state on August 1, 1876,[21] and the university officially opened on September 5, 1877.[22] The City of Boulder City shortened its name to the City of Boulder.

In 1907, Boulder adopted an anti-saloon ordinance.[23] In 1916, statewide prohibition started in Colorado, and ended with the repeal of national prohibition in 1933.[24]

Boulder in 1900

### Housing

[edit]

Median home prices rose 60% from 2010 to 2015 to $648,200.[25] In 2024, the City Council of Boulder repealed a long-standing law that prevented Boulder from increasing new residential units by more than 1% in a year.[26]

In 1959, city voters approved the "Blue Line" city-charter amendment, which restricted city water service to altitudes below 5,750 feet (1,750 m), to protect the mountain backdrop from development. In 1967, city voters approved a dedicated sales tax to acquire open space to contain urban sprawl. In 1970, Boulder created a "comprehensive plan" to dictate future zoning, transportation, and urban planning decisions. Hoping to preserve residents' views of the mountains, in 1972, the city enacted an ordinance limiting the height of newly constructed buildings. In 1974, a Historic Preservation Code was passed. In 1976, a residential-growth management ordinance, the Danish Plan, was passed.[27][28]

## Geography

[edit]

Boulder's rock formations, the Flatirons

The city of Boulder is located in the Boulder Valley, where the Rocky Mountains meet the Great Plains. The Flatirons, slabs of sedimentary stone tilted up on the foothills, are located west of the city and are a widely recognized symbol of Boulder.[29]

Boulder Creek is the primary flow of water through Boulder. The creek was named before the city's founding and its etymology is unknown. It is from Boulder Creek that the city is believed to have taken its name.[citation needed] Boulder Creek has significant water flow, derived primarily from snow melt and minor springs west of the city.[citation needed] The creek flows into St. Vrain Creek east of Longmont, which is a tributary of the South Platte River.

At the 2020 United States census, the city had a total area of 17,514 acres (70.877 km2), including 664 acres (2.689 km2) of water.[7]

The 40th parallel, 40 degrees north latitude, runs through Boulder and can be easily recognized as Baseline Road today.

Boulder lies in a wide basin beneath Flagstaff Mountain just a few miles east of the continental divide and about 25 miles (40 km) northwest of Denver. Arapahoe Glacier provides water for the city, along with Boulder Creek, which flows through the center of the city.[30]

Denver International Airport is located 33 miles (53 km) east-southeast of Boulder.[31]

### Environment

[edit]

In 1899, government preservation of open space around Boulder began, with the Congress of the United States approving the allocation of 1,800 acres (7.3 km2) of mountain backdrop/watershed extending from South Boulder Creek to Sunshine Canyon.

#### Wildlife protection

[edit]

Boulder has created an Urban Wildlife Management Plan which sets policies for managing and protecting urban wildlife.[32] The city's Parks and Recreation and Open Space and Mountain Parks departments have volunteers who monitor parks, including wetlands, lakes, etc., to protect ecosystems.[33] From time to time, parks and hiking trails are closed to conserve or restore ecosystems.[34] Traditionally, Boulder has avoided using chemical pesticides to control the insect population. However, with the threat of West Nile virus, the city began an integrative plan[35] to control the mosquito population in 2003 that includes chemical pesticides. Residents can opt out of the program by contacting the city and asking that their areas not be sprayed.[36]

Under Boulder law, exterminating prairie dogs requires a permit.[37]

In 2005, the city experimented with using goats for weed control in environmentally sensitive areas. Goats naturally consume diffuse knapweed and Canada thistle, and although the program was not as effective as it was hoped, goats will still be considered in future weed control projects. In 2010, goats were used to keep weeds under control at the Boulder Reservoir.[38]

The city's Open Space and Mountain Parks department manages approximately 8,000 acres (32 km2) of protected forest land west of the city, in accordance with a 1999 Forest Ecosystem Management Plan. The plan aims to maintain or enhance native plant and animal species, their communities, the ecological processes that sustain them and to reduce the wildfire risk to forest and human communities.[39]

Autumn in Boulder Snowfall is common in Boulder throughout the winter.

Boulder has a temperate climate typical for much of the state and receives many sunny or mostly sunny days each year. Boulder is considered semi-arid (Köppen: BSk) or humid subtropical (Köppen: Cfa) within the Köppen climate classification due to its relatively high yearly precipitation and average temperatures remaining above 32 °F (0 °C) year-round.[40][41][42][43]

Winter conditions range from generally mild to the occasional bitterly cold. Highs average in the mid to upper 40s °F (7–9 °C). There are 4.6 nights annually where the temperature drops to 0 °F (−18 °C). Because of orographic lift, the mountains to the west often dry out the air passing over the Front Range, shielding the city from precipitation in winter, though heavy snowfalls may occur. Snowfall averages 88 inches (220 cm) per season. Snow depth is usually shallow. Due to the high elevation, a strong warming sun can quickly melt snow cover during the day and Chinook winds bring rapid warm-ups throughout the winter months.[44]

Summers are warm, with frequent afternoon thunderstorms. There are roughly 30 days of 90 °F (32 °C) or above each year.[44] Diurnal temperature variation is typically large due to the high elevation and semi-arid climate. Daytime highs are generally cooler than those of most Colorado cities with similar elevations.

The highest recorded temperature of 104 °F (40 °C) was on June 25, 2012.[45] The record low was −33 °F (−36 °C) on January 17, 1930. The coldest high temperature, −12 °F (−24 °C), was on February 4, 1989. The warmest overnight low was on July 20, 1998, with a temperature of 82 °F (28 °C)[46]

### Bolder Boulder

[edit]

Boulder has hosted a 10 km road run, the Bolder Boulder, on Memorial Day every year since 1979. The race involves over 50,000 runners, joggers, walkers, and wheelchair racers, making it one of the largest road races in the world. It has the largest non-marathon prize purse in road racing.[58] The race culminates at Folsom Field with a Memorial Day Tribute. The 2007 race featured over 54,000[59] runners, walkers, and wheelchair racers, making it the largest race in the US in which all participants are timed and the fifth largest road race in the world.[60]

### Music

[edit]

Founded in 1958, the Boulder Philharmonic Orchestra is a professional orchestra under the leadership of its Music Director Michael Butterman.[61]

### Naked Pumpkin Run

[edit]

Starting in 1998, dozens of people have taken part in a Halloween run down the city's streets wearing only shoes and a hollowed-out pumpkin on their heads. In 2009, local police threatened participants with charges of indecent exposure, and no naked runners were reported in official newscasts, although a few naked runners were observed by locals. Several illegal attempts, resulting in arrests, have been made to restart the run, but no serious effort has been mounted.[72]

### Boulder Cruiser Ride

[edit]

Bicycle riders joining together on Happy Thursday Cruiser Ride

The Happy Thursday Cruiser Ride is a weekly bicycle ride in Boulder Colorado.[73] The Boulder Cruiser Ride grew from a group of friends and friends of friends in the early '90s riding bicycles around Boulder into the social cycling event it is today.[74] Some enthusiasts gather wearing costumes and decorating their bikes; themes are an integral part of the cruiser tradition.[citation needed] Boulder Police began following the cruiser ride as it gained in popularity in the early 2000s.[citation needed]

Issues with underage drinking, reckless bicycle riding, and other nuisance complaints led organizers to drop the cruiser ride as a public event.[75] Returning to an underground format, where enthusiasts must become part of the social network before gaining access to event sites, the Boulder Cruiser Ride has continued as a local tradition.[citation needed] On May 30, 2013, over 400 riders attended the Thursday-night Cruiser Ride in honor of "Big Boy", an elk that was shot and killed on New Year's Day by an on-duty[76] Boulder Police officer.[77]

Trailheads for many popular hikes are located at Chautauqua Park.

Boulder is surrounded by thousands of acres of recreational open space, conservation easements, and nature preserves. Almost 60%, 35,584 acres (144.00 km2), of open space totaling 61,529 acres (249.00 km2) is open to the public.[83]

The unincorporated community of Eldorado Springs, south of Boulder, is home to rock climbing routes.[84] There are climbing routes available in the city open space, including climbing routes of varying difficulty on the Flatirons themselves (traditional protection). Boulder Canyon (sport), directly west of downtown Boulder, has many routes. All three of these areas are affected by seasonal closures for wildlife.[85][86]

Every year on Groundhog Day, Boulder Parks & Open Space hosts a special event at the Chautauqua Ranger Cottage featuring Flatiron Freddy, a stuffed marmot instead of a groundhog.[87]

## Media

[edit]

Main article: Media in Boulder, Colorado

Boulder's main daily newspaper, the Daily Camera, was founded in 1890 as the weekly Boulder Camera, and became a daily newspaper in 1891. The Colorado Daily was started in 1892 as a university newspaper for CU Boulder. Following many heated controversies over Colorado Daily's political coverage, it severed its ties to the university in 1971. From 1996 to 2000, the Boulder Planet competed with the Boulder Weekly as a free weekly.[97]

Newspaper conglomerate Scripps acquired the Colorado Daily in 2005 after its acquisition of the Camera in 1997, leaving the Boulder Weekly as the only locally owned newspaper in Boulder. Scripps relinquished its 50 percent ownership in both daily papers in early 2009 to Media News Group. Boulder Magazine, a lifestyle magazine, was founded in 1978.[98] Boulder Magazine is published three times per year.

Boulder is part of the Denver market for television stations, and it receives many radio stations based in Denver or Ft. Collins. For cable television, Boulder is served by Comcast Cable. The city operates public service Boulder 8 TV on cable (high- and standard-definition), which airs, live-streams and archives council meetings. With its in-house video production facilities, it also produces news, talk and informational programming.[99] Over-the-air television reception is poor in the western part of the city because of interference from mountains.

Non-commercial community radio station KGNU was founded in 1978[100] and commercial music station KBCO in 1977. KBCO programs an adult album alternative format and is owned and operated by iHeartMedia. KBCO moved its studios from Boulder to the Denver Tech Center in 2010.[101] It maintains the Boulder license and transmits from atop Eldorado Mountain south of Boulder.[102]

KVCU, also known as Radio 1190, is a non-commercial radio station run with the help of university-student volunteers. KVCU started broadcasting in 1998.[103]

NPR programming is heard over KCFC 1490 AM, operated by Colorado Public Radio, and simulcasting Denver station KCFR 90.1.

KRKS-FM 94.7, owned and operated by Salem Media Group and affiliated with SRN News, offers a Christian talk and teaching format, and has its transmitter located on Lee Hill, northwest of Boulder.

The University of Colorado Press, a non-profit co-op of various western universities, publishes academic books, as do Lynne Rienner Publishers, Paradigm Publishers, and Westview Press.[104] Paladin Press book/video publishers and Soldier of Fortune magazine both have their headquarters in Boulder.[105][106] Paladin Press was founded in September 1970 by Peder Lund and Robert K. Brown. In 1974, Lund bought out Brown's share of the press, and Brown founded Soldier of Fortune magazine in 1975.[107]

## Infrastructure

[edit]

### Transportation

[edit]

The city from northbound US 36 as the highway descends into Boulder

Since Boulder has operated under residential growth control ordinances since 1976, the growth of employment in the city has far outstripped population growth. Considerable road traffic enters the city each morning and leaves each afternoon, since many employees live in Longmont, Lafayette, Louisville, Broomfield, Westminster, and Denver. Boulder is served by US 36 and a variety of state highways. Parking regulations in Boulder have been explicitly designed to discourage parking by commuters and to encourage the use of mass transit, with mixed results.[108]

Over the years, Boulder has made significant investments in the multi-modal network. The city is now well known for its grade-separated bicycle and pedestrian paths, which are integrated into a network of bicycle lanes, cycle tracks, and on-street bicycle routes. Boulder provides a community transit network that connects downtown, the University of Colorado campuses, and local shopping amenities. Boulder has no rail transit. Local and regional shuttle busses are funded by a variety of sources. Due in part to these investments in pedestrian, bicycle, and transit infrastructure, Boulder has been recognized both nationally and internationally for its transportation system.[109]

In 2009, the Boulder metropolitan statistical area (MSA) ranked as the fourth highest in the United States for percentage of commuters who biked to work, at 5.4 percent.[110] In 2013, the Boulder MSA ranked as the fourth lowest in the United States for percentage of workers who commuted by private automobile, at 71.9 percent. During the same time period, 11.1 percent of Boulder area workers had no commute whatsoever: they worked out of the home.[111]

#### Bus service

[edit]

Boulder has an extensive bus system operated by the Regional Transportation District (RTD). The HOP, SKIP, JUMP, Bound, DASH and Stampede routes run throughout the city and connect to nearby communities with departures every ten minutes during peak hours, Monday-Friday. Other routes, such as the 204, 205, 206, 208 and 209 depart every 15 to 30 minutes. Regional routes, traveling between nearby cities such as Longmont (BOLT, J), Golden (GS), and Denver (Flatiron Flyer,[112] a bus rapid transit route), as well as Denver International Airport (AB), are also available. There are over 100 scheduled daily bus trips on seven routes that run between Boulder and Denver on weekdays.[113]

#### Railroads

[edit]

Freight service is provided by Union Pacific and BNSF.

Currently there is no intercity passenger service. The last remaining services connecting the Front Range cities ceased with the formation of Amtrak in 1971.

##### Future transit plans

[edit]

Front Range Passenger Rail is a current proposal (as of 2023) to link the cities from Pueblo in the south, north to Fort Collins and possibly to Cheyenne, Wyoming.[114]

A 41-mile (66 km) RTD commuter rail route called the Northwest Rail Line, also known as the B Line, is proposed to run from Denver through Boulder to Longmont, with stops in major communities along the way. The Boulder station is to be north of Pearl Street and east of 30th Street. At one time this commuter rail service was scheduled to commence in 2014, but major delays have ensued. In 2016, an initial 6-mile (9.7 km) segment opened, reaching from downtown Denver to southern Westminster at Westminster Station.[115] The remaining 35 miles (56 km) of the Northwest Rail Line is planned to be completed by 2044, depending upon funding.[116]

These future transit plans, as well as the current Flatiron Flyer Bus Rapid Transit route, are part of FasTracks, an RTD transit improvement plan funded by a 0.4% increase in the sales tax throughout the Denver metro area. RTD, the developer of FasTracks, is partnering with the city of Boulder to plan a transit-oriented development near Pearl and 33rd Streets in association with the proposed Boulder commuter rail station. The development is to feature the Boulder Railroad Depot, already relocated to that site, which may be returned to a transit-related use.

#### Cycling

[edit]

Boulder, well known for its bicycle culture, has hundreds of miles of bicycle-pedestrian paths, lanes, and routes that interconnect to create a renowned network of bikeways usable year-round. Boulder has 74 bike and pedestrian underpasses that facilitate safer and uninterrupted travel throughout much of the city. The city offers a route-finding website that allows users to map personalized bike routes around the city,[117] and is one of five communities to have received a "Platinum Bicycle Friendly Community" rating from the League of American Bicyclists.[118]

The headquarters of the free and non-obligatory hospitality exchange network for cyclists, Warm Showers, is based in Boulder.[119]

In May 2011, B-cycle bike-sharing opened in Boulder with 100 red bikes and 12 stations.[120]

#### Airport

[edit]

Boulder Municipal Airport is located 3 miles (4.8 km) northeast of central Boulder, is owned by the City of Boulder and is used exclusively for general aviation, with most traffic consisting of single-engine airplanes and glider aircraft.[121]

Boulder was a setting for Stephen King's book The Stand (1978), as the gathering point for some of the survivors of the superflu. King lived in Boulder for a little less than a year, beginning in the autumn of 1974, and wrote The Shining (1977) during this period.[124]

The television sitcom Mork & Mindy (1978–1982) was set in Boulder, with 1619 Pine St. serving as the exterior shot of Mindy's home.[125] The New York Deli, a now closed restaurant in the Pearl Street Mall, was also featured prominently in the series.[126]
