Black Hawk’s Mining Boom to Casino Transformation
Black Hawk, Colorado went from boom to bust to boom again. Back in 1899, over 2,000 people lived in this mining town.
Then the mines dried up. After World War I, folks left in droves while floods wrecked what stayed.
By the 1980s, just a few hundred people hung on as buildings fell apart. The town faced death until a bold plan emerged.
In 1990, voters said yes to gambling, and the first casinos opened in 1991. Soon after, cash poured in—over $1 billion worth.
Now Black Hawk hosts 20,000 visitors daily, though its new 33-story towers have changed the old town beyond recognition.
The story of this dramatic transformation awaits at Gregory Street, where a 1932 monument still stands.

John Gregory’s Lucky Strike Sparked a Gold Rush
John Gregory found gold in Gregory Gulch on May 6, 1859, changing Colorado forever. His strike brought thousands of gold-hungry folks to the area within weeks.
The narrow gulch quickly filled with tents, shacks, and stores as people rushed to get rich. Gregory Gulch got the nickname “Richest Square Mile on Earth.”
Black Hawk Point started as a mining camp in what was then Kansas Territory, growing from nothing to a busy settlement almost overnight.
Mills and Smelters Made Black Hawk the Industrial Hub
Nathaniel Hill built Colorado’s first working ore smelter in Black Hawk in 1868, fixing a big problem for miners. Before his smelter, miners couldn’t process the deep sulfide ores that held most of the gold.
Black Hawk sat right on North Clear Creek, making it perfect for water-powered mills. People called it the “City of Mills” because of all the ore processing.
While nearby Central City focused on mining, Black Hawk became the place where raw ore turned into valuable metal.
Trains Brought More People and Money to Town
The Colorado Central Railroad came to Black Hawk in 1872, linking the mountain town to Denver markets. This train connection made shipping gold easier and brought more supplies and people to the booming town.
Black Hawk officially became a city on June 12, 1886, as more people moved in. By 1899, over 2,000 people lived in Black Hawk.
The town thrived as the main supply and processing center for all the mines in the area.

The Gold Ran Out and People Left
Mining crashed after World War I ended in 1918, hitting Black Hawk hard. The town faced money troubles and repeated flooding that wrecked buildings and roads.
People moved away, with the population dropping from 2,000 to just 250 by 1920. Only one mill kept running by the 1920s.
Empty buildings lined the streets as jobs dried up and families looked for better chances elsewhere.
Hard Times Hit the Mountain Town
Gold prices jumped briefly in the 1930s, giving Black Hawk a small boost during the Great Depression. Workers fixed up the nearby Central City Opera House in 1932, bringing a few tourists to the area.
Trains stopped coming to Black Hawk in 1941 as cars became more popular. Water and sewer problems kept getting worse with no money to fix them.
The town nearly became a ghost town, with old buildings and fewer people each year to pay taxes.
Old Buildings Got Protected But Money Problems Grew
The government named Central City and Black Hawk a National Historic District in 1966, helping save old mining-era buildings. This protection didn’t solve the money problems, though.
Most people had to drive to jobs in other towns just to make a living.
Both towns struggled with growing costs to keep basic services running while tax money kept shrinking. By the 1980s, only a few hundred people remained and Central City’s water supply failed state health tests.

South Dakota’s Gambling Town Showed a Way Forward
Deadwood, South Dakota made gambling legal in 1989 to save its historic buildings, catching Black Hawk leaders’ attention. They saw how Deadwood changed from a dying town to a tourist spot quickly.
Black Hawk joined with Central City and Cripple Creek to push for the same fix in Colorado. They sold gambling as a way to fund historic preservation.
Lobbyist Freda Poundstone helped create a winning plan for Amendment 4, which would allow limited gambling in the old mining towns.
Voters Said Yes to Cards and Slots Despite the Governor’s Concerns
Colorado voters approved Amendment 4 in November 1990 with 57% saying yes, even though Governor Roy Romer warned it might lead to too much building.
The new law allowed gambling with a $5 maximum bet in specific historic areas.
Money from gambling taxes would go to historic projects across Colorado, with some also going to the counties and towns. The rules made casinos follow building guidelines to keep the historic look of the towns.
Poker Tables and Slot Machines Moved Into Old Buildings
The first two small casinos opened in Black Hawk on October 1, 1991, set up in fixed-up historic buildings. These modest places brought in about $20,000 daily, showing the potential for success.
Black Hawk had a big edge over Central City because it sat right on Highway 119, making it easier for visitors to reach. The town also had less strict building rules than Central City, allowing for bigger casinos.
Early success brought more investors looking to cash in on Colorado’s new gambling scene.
Bulldozers and Cranes Reshaped the Entire Town
Over $1 billion poured into Black Hawk during the next 30 years, completely rebuilding the small mountain town. Massive earth-moving equipment reshaped the canyon to create flat land for large casinos.
Historic homes got picked up and moved to terraced neighborhoods on the hillsides. The Ameristar casino built a 33-story hotel tower that stands taller than the surrounding mountains.
The physical landscape changed so dramatically that old-timers wouldn’t recognize the place.
Gambling Brought Big Money But Lost the Town’s Soul
Black Hawk now generates over 85% of all Colorado’s gambling revenue, a remarkable turnaround for a town that nearly vanished.
More than 20,000 visitors come to Black Hawk daily, though only 127 people actually live there. The town contributes over $100 million annually in taxes for state preservation and education funds.
Many critics point out that the massive modern casinos destroyed the very historic character the gambling was supposed to preserve.
The tiny mining town transformed completely into a mini-Las Vegas, trading its past for a profitable future.
