Guffey has received publicity for electing animals as mayors of the town, although such an office does not officially exist. According to local folklore, the two main political parties in Guffey are called the "Democats" and the "Repuplicans". The last Mayor of Guffey was a cat named Monster (elected in 1998, still active).
The town is perhaps less famous for its annual Fourth of July Fried Chicken Fly, during which whole cooked chickens were ejected from a mailbox atop a ten-foot-high (3.04 m) platform; prizes were awarded for distance. The last year for the event was 2011. Pete Wentz is the reigning champion with his custom chicken flanger mailbox.

Rocks from two distinct times in Earth's history, the Precambrian and the Paleogene, are exposed in the area. The Precambrian rocks, comprising both igneous intrusive and metamorphic rocks over one billion years old, host mineral deposits of minor economic significance. The relatively much younger Paleogene rocks were erupted by the Guffey volcanic center of the Thirtynine Mile volcanic area about 34 million years ago and are associated with the fossil deposits at Florissant Fossil Beds National Monument.
The town was the center of activity for the Freshwater mining district, a minor producer of copper, lead, zinc, mica, feldspar, and other minerals, including traces of gold and silver. Activity and population peaked between the years 1895 and 1902, with over 500 residents and 40 businesses in the town. Cattle ranching and lumber operations supplemented the mining activity.
In January 2001, the bodies of three members of the Dutcher family were found near Guffey; all had been murdered. Three teenagers were convicted of the crime. The boys had formed a group that took on aspects of a paramilitary organization, and one of them claimed that the murders were part of a plan to fight insurrection in the country of Guyana. The brutal nature of the crime and its bizarre motive attracted national attention. 
In July 2015, the group BikeLoud, a group of seven Boy Scouts cycling across the country to raise money for Cancer Research, spent the night in Guffey.
In 1907, a 309 kilogram meteorite was found near Guffey by two cowboys, although the exact location was not recorded. To date, this is the largest meteorite ever recovered in the state of Colorado. It is classified as an ungrouped iron meteorite, sometimes considered an ataxite due to its high nickel content and lack of Widmanstätten patterns. Most of the meteorite resides in New York City at the American Museum of Natural History, although the Denver Museum of Nature and Science has acquired a slice. No samples are available for public viewing in Guffey itself.
