Granby is noted as being the "Oldest Mining Town in the Southwest". There are many chat piles scattered about Granby today as evidence of the boom of lead and zinc mining as part of the Tri-State district back in the early 20th century.
In the early 19th century, after the United States bought the land as part of the Louisiana Purchase, homesteading was the main reason to move there. Among the American settlers who came was a man named Madison Vickery. According to official history, Vickery discovered lead while digging for water. News of Vickery's strike, around 1850, spread quickly. The resulting flood of prospectors was so wild the time came to be known as the Granby Stampede. By 1855, the population swelled to 8,000.
By 1859, over 25 million tons of lead had been shipped from Granby mines. Granby had the largest lead mining and smelting operations in the state and was one of the most important lead resources in the country. During the civil war, both North and South came to Granby for ammunition. Granby lead flew both ways during the Civil War. In October 1862, the Battle of Granby finally established Union control of the mines, though the smelter was destroyed in the fighting. After the war, mining resumed with a fury, aided by new technology and improved rail transportation. In 1868, Granby's petition for incorporation was accepted by the state and in 1875 the city of Granby was officially chartered. The mines thrived through the first and second World Wars, but then the payable ore deposits began to run out.
Granby contains two cemeteries, the Granby Memorial Cemetery and a more antiquitated cemetery often referred to as the "Old Granby Cemetery."
