Boulder's iconic rock formations, the "Flatirons
The city of Boulder is in Boulder Valley where the "Rocky Mountains meet the "Great Plains. West of the city are slabs of sedimentary stone tilted up on the foothills, known as the "Flatirons. The Flatirons are a widely recognized symbol of Boulder.
The primary water flow through the city is "Boulder Creek. The creek was named well ahead of the city's founding, for all of the large granite boulders that have cascaded into the creek over the eons. It is from Boulder Creek that Boulder city is believed to have taken its name. Boulder Creek has significant water flow, derived primarily from snow melt and minor springs west of the city. The creek is a tributary of the "South Platte River.
According to the "United States Census Bureau, the city has a total area of 25.7 square miles (66.5 km2). 24.7 square miles (63.9 km2) of it is land and 1.0 square mile (2.6 km2) of it (3.97%) is water.

Autumn in Boulder brings many sunny days
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. The city is commonly claimed to be semi-arid, but under the "Köppen climate classification, the city has a "hot-summer humid continental climate (Köppen Dfa). Winter conditions range from generally mild to the occasional bitterly cold, with highs averaging in the mid to upper 40s °F (7–9 °C). There are 4.6 nights annually when the temperature reaches 0 °F (−18 °C). Because of "orographic lift, the mountains to the west often dry out the air passing over the "Front Range, often shielding the city from precipitation in winter, though heavy falls may occur. Snowfall averages 88 inches (220 cm) per season, but snow depth is usually shallow; a strong warming sun due to the high elevation can quickly melt snow cover during the day, and "Chinook winds bring rapid warm-ups throughout the winter months. Summers are very warm and dry, with 30 days reaching 90 °F (32 °C) or above. "Diurnal temperature variation is typically large year-round due to the high-elevation dry climate. Daytime highs are generally cooler than most other "Front Range cities with similar elevations. However, Boulder's nighttime lows, particularly during winter, are some of the mildest in the state. Daily average temperatures remain above 32 °F (0 °C) year-round.
The highest recorded temperature of 104 °F (40 °C) occurred most recently within the city on June 25, 2012. The lowest temperature recorded in Boulder was −33 °F (−36 °C) on January 17, 1930. The lowest maximum temperature in Boulder, −12 °F (−24 °C), was on February 4, 1989. In contrast, on June 24, 1954, Boulder's overnight low temperature did not drop below 80 °F (27 °C).

The 2010 head count was officially between 8,000 and 15,000 with some discrepancy between the local papers and the University administrators (who have been thought to have been attempting to downplay the event). Eleven "citations were given out whereas the year before there were only two. 2011 was the last year of mass 420 partying at CU as the university, in 2012, took a hard stance against 420 activities, closing the campus to visitors for the day, using smelly fish fertilizer to discourage gathering at the Norlin Quad, and having out-of-town law enforcement agencies help secure the campus. In 2013, April 20 fell on a Saturday; the university continued the 420 party ban and, again, closed the campus to visitors. In 2015 the government conceded and once again opened the park to visitors on April 20.

Some enthusiasts gather wearing costumes and decorating their bikes; themes are an integral part of the cruiser tradition. Boulder Police began following the cruiser ride as it gained in popularity. Issues with underage drinking, reckless bicycle riding, and other nuisance complaints led organizers to drop the cruiser ride as a public event. 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. 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 Boulder Police officer.

Economy and industry
The Boulder MSA had a gross metropolitan product of $18.3 billion in 2010, the 110th largest metropolitan economy in the United States.
In 2007, Boulder became the first city in the USA to levy a "carbon tax.
In 2013, Boulder appeared on "Forbes magazine's list of Best Places for Business and Careers.
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.
Boulder, Colorado, a city of just over 100,000 people, is located approximately 30 miles northwest of Denver at the foothills of the Rocky Mountains. Boulder is home to the University of Colorado, whose 30,000 students swell the city's population during the academic year. 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 also provides an innovative community transit network that connects downtown, the University of Colorado campuses, and local shopping amenities. While the city has no rail transit, local and regional shuttle busses are funded by a variety of sources and emphasize minimal headways, enhanced route identity, easy fare payment, and community input in design (RTD, 2005). Due in part to these investments in pedestrian, bicycle, and transit infrastructure, Boulder has been recognized both nationally and internationally for its transportation system.
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, 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.
Future transit plans
A 41-mile RTD "commuter rail route called the Northwest Rail 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 segment opened, reaching from downtown Denver to southern "Westminster at West 71st Avenue and Federal Boulevard. The remaining 35 miles of the Northwest Rail Line is planned to be completed by 2044, depending upon funding.
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.
Boulder, well known for its "bicycle culture, boasts 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.
In May 2011, "B-cycle bike-sharing opened in Boulder with 100 red bikes and 12 stations.
"Boulder Municipal Airport is located 3 miles (4.8 km) from 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.
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 in 1899.
Since then, Boulder has adopted a policy of controlled urban expansion. 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), in an effort to protect the mountain backdrop from development. In 1967, city voters approved a dedicated sales tax for the acquisition of open space in an effort to contain "urban sprawl. In 1970, Boulder created a "comprehensive plan" that would 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. A Historic-Preservation Code was passed in 1974, and a residential-growth management ordinance (the Danish Plan) in 1976.
Effective growth management has resulted in rapid appreciation of housing values with the median home price rising 60% over the period 2010 to 2015 to $648,200.
Prairie Dogs enjoy special protection in Boulder.
The City of Boulder has created an Urban Wildlife Management Plan which sets policies for managing and protecting urban wildlife. Also, the city's parks department has volunteers who monitor parks (including wetlands, lakes, etc.) to protect ecosystems. From time to time, parks and hiking trails are closed to conserve or restore ecosystems. Traditionally, Boulder has avoided the use of chemical "pesticides for controlling the insect population. However, with the threat of "West Nile Virus, the city began an integrative plan 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.
Under Boulder law, extermination of "prairie dogs requires a permit.
Also 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 the future weed control projects. In 2010, goats were used to keep weeds under control at the Boulder Reservoir.
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 the following year. 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. 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. Boulder Magazine is published three times per year.
Boulder is part of the "Denver market for television stations, and it also receives many radio stations based in Denver or "Ft. Collins. For cable television, Boulder is served by "Comcast Cable. Over-the-air television reception is poor in the western part of the city because of interference from mountains.
"Paladin Press book/video publishers and "Soldier of Fortune magazine both have their headquarters in Boulder. 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 moved on to found Soldier of Fortune magazine the following year.
Non-commercial "community radio station "KGNU was founded in 1978 and commercial music station "KBCO in 1977. KBCO programs an "adult album alternative format and is owned and operated by "Clear Channel Communications. KBCO transmits from atop "Eldorado Mountain south of Boulder.

Pearl Street Mall in Boulder
One of the most popular sections of Boulder is the famous "Pearl Street Mall, home to numerous shops and restaurants. This four-block pedestrian mall is a social hotspot in Boulder, with dozens of restaurants of all kinds and specialty stores that include artisan shops and unique gadget shops. In the summer and on weekends, many street shows and acts can be found throughout the mall, along with street vendors and henna tattoo artists.
Boulder's traditional Downtown area, including the Pearl Street Mall, is in the western part of present-day Boulder. During the 1950s and 1960s, the city grew to the east, since the west side is bounded by the foothills. Downtown is host to a variety of restaurants, bars, and boutique stores. However, it has few grocery, hardware, or department stores and is therefore more of a "shopping destination" than a neighborhood with stores supporting the local population.
South of Pearl Street and adjacent to the CU-Boulder campus is another historic shopping center, "The Hill. Featuring some of the city's landmark stores and venues, such as Albums on the Hill and the "Fox Theatre, The Hill has been the center of college life for many of the nearby sororities and fraternities.
The "Twenty Ninth Street retail district opened in October 2006, located in central Boulder on the site of the former "Crossroads Mall, east of Downtown.
Near the "Pearl Street Mall the "Farmers' Market opens every Saturday morning and Wednesday evening, April through October on 13th Street next to Central Park. The market was started in 1986 by regional farmers.
Boulder has seven official "sister cities:
Landmarks representing Boulder's connection with its various sister cities can be found throughout the city. Boulder's Sister City Plaza – dedicated on May 17, 2007 – is located on the east lawn of Boulder's Municipal Building. The plaza was built to honor all of Boulder's sister city relationships. The "Dushanbe Tea House is located on 13th Street just south of the Pearl Street Mall. Dushanbe presented its distinctive tea house as a gift to Boulder in 1987. It was completed in Tajikistan in 1990, then shipped to Boulder where it was reassembled and opened to the public in 1998. A mural representing the relationship between Boulder and Mante, Mexico was dedicated in August 2001. The mural, which was painted by Mante muralist Florian Lopez, is located on the north-facing wall of the Dairy Center for the Performing Arts.
More information about Boulder's sister city relationships can be found at Boulder's official website.
