In Montrose in the summer of 1912, a 17-year-old fighter who called himself Kid Blackie knocked down his friend and boxing opponent Fred Wood to win his first sort-of professional fight. He split the $40 purse with Wood.
Seven years later, Kid Blackie had a different nickname, the Manassa Mauler, and a new title: heavyweight champion of the world.
On July 4, 1919, 24-year-old William Harrison "Jack" Dempsey destroyed the reigning champion, giant Jess Willard in Toledo, Ohio. Willard surrendered after three rounds.
Although Dempsey was some 50 pounds lighter than Willard and several inches shorter, he "snapped Willard's jaw, pried loose six teeth, broke his cheekbone, squashed his nose, (and) closed one eye," wrote author Toby Smith.
Few boxing fans had ever seen someone punch as hard as Dempsey did against Willard. Afterward, writer Damon Runyon dubbed Dempsey the Manassa Mauler, combining Dempsey's fighting style with his birthplace in the San Luis Valley.
However, a number of Colorado communities share in Dempsey's legacy.
Montrose played an important role beyond the 1912 fight. The Dempsey family spent several years there when the Gunnison Tunnel irrigation project was being built.
Dempsey's mother, Celia, operated a restaurant for the tunnel workers until 1909. The future fighter helped wash dishes and bus tables.
But the Dempsey family moved a lot, and records of when and where they lived are not always clear.
Smith reported they moved to Delta in mid-1907. However, the Delta County Historical Society has records showing that Dempsey's father, Hyrum, worked at the Delta Brick and Tile Factory in 1905.
Other dates in Dempsey's young life are also disputed.
Originally from West Virginia, Celia and Hyrum Dempsey arrived in Manassa before the turn of the century, but left in 1903 or 1904.
They moved first to Creede, where Celia worked in a boarding house, then Leadville, where she became ill.
After a brief stint in Denver, it was back to the Western Slope, first to Wolcott, then Steamboat Springs, Rifle, on to a ranch south of Montrose, and finally to Montrose.
Where ever they lived, young Dempsey fought because boxing was a popular activity for poor youngsters.
Encouraged by his mother, the boy then known as Harry decided he would become a champion one day.
After Montrose, Hyrum moved the family to Lakeview, Utah, where Dempsey graduated from elementary School in 1911, just before his 16th birthday.
Soon afterward he began riding the rails, mostly to towns in Colorado, where he found work as a miner or ranch hand, anything to obtain food.
He also boxed. One friend estimated Dempsey fought 450 bouts in the saloons, hotels and bordellos of Colorado and Utah. Most fights were just for meals or a few dollars.
Often, Dempsey said, he would walk into a saloon and offer to fight any takers for a dollar.
Dempsey began to develop his boxing skills then. He learned to duck and weave, to hit with both fists, to observe his opponents and fight to their weaknesses.
He developed a reputation as a tough brawler, though peaceful outside the ring.
He learned from his older brother, Bernie, a not-very- successful professional fighter. Bernie sometimes called himself "Jack" Dempsey, and his younger brother appropriated that name.
The teenage Dempsey also learned pugilistic technique from friends Pat and Andy Malloy in Telluride, where Dempsey worked as a miner. He fought multiple fights there and in towns from Gunnison to Salida to the Front Range.
He defeated a local champion in Cripple Creek in 1913. He is believed to have fought at the Park Opera House in Grand Junction, but the date and name of his opponent are unknown.
A 1915 exhibition in Durango, in which he knocked his buddy Andy Malloy down multiple times, is pictured in a mural on the wall of the El Rancho Lounge in Durango.
That same year, Dempsey attacked four men at the Grand Junction Hotel and Lunch Counter after he recognized them as a crew of thugs that had earlier robbed Dempsey and a Denver reporter at gunpoint.
The reporter described Dempsey as "a destructive dervish" who easily dispatched the four robbers and recovered the stolen money.
In 1916, Dempsey was lured to New York by a fight promoter, but the trip was a disaster. He lost multiple bouts to experienced boxers and was bilked out of his meager share of purses.
In 1917, he fought Pueblo's Fireman Jim Flynn, an experienced heavyweight with a national reputation. Dempsey lost by a technical knockout in the first round, but in a rematch a year later, Dempsey knocked Flynn out in the first round.
By then, Dempsey had spent almost a year in Oakland, California, with manager Jack Kearns. He had a succession of victories over recognized boxers, including seven knockouts in a row. He established a reputation that allowed him to challenge Willard for a title in 1919.
Dempsey held the heavyweight crown for more than seven years, and throughout the 1920s, he and Babe Ruth were the two best known U.S. sports figures.
While Ruth earned $80,000 a year at his peak, Dempsey made almost four times that in one fight. His bouts produced the first million-dollar gates in boxing history.
In 1920, Dempsey's ex-wife, a dance hall girl from Utah, accused him of dodging the draft in World War I.
He was exonerated when it was proved he had legally obtained an exemption as the sole breadwinner for his family. Still, the epithet "slacker" dogged him for years.
One of his best-remembered title defenses came in 1923, when he was knocked out of the ring by Argentinian Louis Firpo.
He was pushed back by sportswriters, returned to the ring and KO'd Firpo in the second round.
His most famous fights were two losses to Gene Tunney, first in a 10-round decision in 1926, then in a famous rematch in 1927 with what became known as "the long count."
Dempsey knocked Tunney down hard in the seventh round of the 1927 fight, but didn't retreat to a neutral corner. Tunney laid on the canvas for nearly 15 seconds while the ref waved Dempsey away.
Then Tunney got up and won another decision.
Dempsey never regained his title, but he remained a popular ex-champion. Soon after the Tunney fight, he gave up his professional career but continued to stage exhibition fights.
Eventually, he opened a restaurant in New York City, where he held court and greeted customers well into the 1970s.
Dempsey returned to Colorado several times. He made stops in Denver and was inducted into Colorado's Sports Hall of Fame in 1965.
He went fishing in Gunnison. He traveled to Manassa in the early 1960s to dedicate his boyhood home as a museum.
