With help from locals, Brown began building a one room schoolhouse on the southwest corner of 15th and Walnut Street. The building was finished by October and became the first structure in Colorado designed specifically for education. It served as Boulder’s schoolhouse until 1872 when a larger school was built. The original frame was relocated to 11th and Walnut and converted to a private residence before being destroyed by a fire in 1890.
The Ward Mining District was formed; named after Calvin
Ward.
Andrew J. Macky erected the first frame building in Boulder

Congress voted to create the new Colorado Territory in February of 1861. This decision was the continuation of a vote taken by Colorado settlers in 1859 where they decided to become a territory rather than a state. This meant that the administrative costs of governance would be handled by the federal government until the territory became a state. The admission of new territories was a contentious issue in the House of Representatives until the Civil War began, which cleared the way for the admission of the free Colorado Territory.

Boulder County was formed on November 11, 1861.

Adults over the age of 21 were eligible to claim 160 acres of land provided they cultivated the land and improved it with structures. After five years the land was theirs to own for a small filing fee. The act was part of the federal government’s efforts to encourage settlement of the west, but was only nominally successful as it proved extremely difficult for individuals to create productive farms on these small plots of land.

Colorado became the 38th state in the Union on August 1, 1876 with a proclamation by President Ulysses Grant.

Coal mining in the area began on her property in 1887 and Mary designated 150 acres of her land for a new town which she named after her husband Lafayette.

The Boulder Creek "100-year" flood damaged
the town. In May of 1894, 60 straight hours of warm rain combined with a rapid snowmelt to create a 100 year flood that ravaged Boulder. The floodwaters covered most of the town, inundating the area from Walnut Street to Arapaho and from 9th Street to the city limits in the east. In addition it washed out many houses as well as the bridges on 6th street and 12th street. The town was split in two as transportation and communication services were knocked out. Reconstruction began soon after the flood but proved an arduous process.

Tungsten was discovered in the mountains west of Boulder. Extending in a 9.5 mile strip from Arkansas Mountain to Nederland, it was one of the most productive veins in the region. The discovery coincided with the rising demand for tungsten and a number of eastern financiers began investing in the region. The ore, which sold for $2 per unit in 1901, reached $16 per unit by 1916 as the United States’ entry into World War One greatly increased the demand. By that time Boulder County was the world’s leading producer of tungsten ore.

On January 20, a stray spark caused a large explosion at Monarch Mine No. 2, a part of Colorado’s northern coal field. The explosion occurred at 6:20 A.M, killing eight miners who were working the graveyard shift. Had the explosion occurred an hour later, over 100 dayshift miners would have been working in the mine. As it was two miners survived, but debris and poisonous gases prevented rescuers from reaching the other victims in time. The mine was permanently closed and a granite gravestone was erected at the current site of the Flatirons Mall.

The Denver-Boulder turnpike was completed and opened to traffic in 1952. The highway was the first of its kind in Colorado and preceded the introduction of the Interstate system. It cost 25 cents for a trip from Denver to Boulder and provided a pleasant drive through rolling green farmland. Boulder’s population began to explode around this time and traffic volume so far exceeded expectations that the turnpike fees paid off the $6.3 million in bonds in 15 years. As a result the toll road became a free public road in 1967, becoming the first in the country to do so.

Now a historical landmark, the depot was used as an event center until acquired by the city in 2008 and moved to Boulder Junction, near the Northern and Santa Fe railroad.

The state of Colorado purchased 565 acres below the flatirons with the intent of turning it over to the federal government for the construction of the National Center for Atmospheric Research. An exception was added to Boulder’s "Blue Line", a city policy which controlled settlement in the foothills west of Boulder by denying water to these houses. With that out of the way, construction began on the Mesa Lab in 1964. The structure was modeled after the Mesa Verde cliff dwellings in southwest Colorado and the sandstone building material was designed to blend into the flatiron landscape that surrounded it. Today NCAR works closely with the University of Colorado and conducts cutting edge research in the field of atmospheric science.

Pearl Street is closed to automobile traffic and the pedestrian mall is opened. With Boulder’s population explosion in the 60’s and 70’s, Boulder’s downtown area was becoming an afterthought as shopping centers sprung up on the outskirts of town. Local architect Carl Worthington proposed the idea of a pedestrian mall modeled after European walking plazas. The city received a grant from the federal government and a number of local organizations worked together to make the plan a reality. The mall revitalized downtown Boulder and is one of the most successful walking malls in the country.

The Dushanbe Tea House was erected on 13th street. Beginning in 1987, forty artisans from the city of Dushanbe, Tajikistan constructed the exquisite building in traditional style. It was then disassembled and shipped to Boulder in 200 separate crates in 1990. A lack of funds and arguments over the best location delayed the project over the next seven years. These problems were finally ironed out and construction began on the tea house in 1997 before it opened to the public the following year.

On Labor Day a wildfire broke out in Four Mile Canyon northwest of Boulder. A dry August and wind speeds up to 60 mph created conditions ideal for the fire which ripped through the canyon. 6,000 acres were ablaze by the end of the day, forcing the evacuation of 3,000 residents in the area. Firemen contained the blaze a week later but not before 169 homes were destroyed, making it the most destructive fire in Colorado history at the time.
The 25th anniversary of the Boulder Farmer’s Market occurred. In 1986 a group of local farmers decided to organize a farmer’s market to combat the pricing out of small farmers. Markets had occurred informally in the preceding years but had met with little success. This time the farmers secured a permit from the city and set up in Central Park. The following year the market became a non-profit corporation and began collecting a small percentage of food sales to offset operating costs. The market continued to grow and today it is a popular community event in Boulder that helps promote local agriculture.
