History
Name
The first prospectors in the area built a stockade known as Fort Mary B named after Mary Bigelow, who was the only woman in the party. The town of Breckenridge was founded in November 1859 and named for prospector Thomas Breckenridge. General George E. Spencer persuaded the citizens to change the spelling of the town's name to Breckinridge in honor of U.S. Vice President John Cabell Breckinridge in the hopes of gaining a post office. Spencer succeeded in his plan and on January 18, 1860, the Breckinridge post office became the first U.S. post office between the Continental Divide and Salt Lake City. Thirty days after John Breckinridge accepted a commission as a brigadier general in the Confederate States Army on November 2, 1861, the loyal Union town changed its name back to the original Breckenridge on December 2, 1861.
Discovery

Prospectors entered what is now Summit County (then part of Utah Territory) during the Pikes Peak Gold Rush of 1859, soon after the placer gold discoveries east of Breckenridge near Idaho Springs. Breckenridge was founded to serve the miners working rich placer gold deposits discovered along the Blue River. Placer gold mining was soon joined by hard rock mining, as prospectors followed the gold to its source veins in the hills. Gold in some upper gravel benches east of the Blue River was recovered by hydraulic mining. Gold production decreased in the late 1800s, but revived in 1908 by gold dredging operations along the Blue River and Swan River. The Breckenridge mining district is credited with production of about one million troy ounces (about 31,000 kilograms) of gold.
The gold mines around Breckenridge are all shut down, although some are open to tourist visits. The characteristic gravel ridges left by the gold dredges can still be seen along the Blue River and Snake River, and the remains of a dredge are still afloat in a pond off the Swan River.
Notable among the early prospectors was Edwin Carter, a log cabin naturalist who decided to switch from mining to collecting wildlife specimens. His log cabin, built in 1875, still stands today and has been recently renovated by the Breckenridge Heritage Alliance with interactive exhibits and a small viewing room with a short creative film on his life and the early days around Breckenridge.
Harry Farncomb found the source of the French Gulch placer gold on Farncomb Hill in 1878. His strike, Wire Patch, consisted of alluvial gold in wire, leaf and crystalline forms. By 1880, he owned the hill. Farncomb later discovered a gold vein, which became the Wire Patch Mine. Other vein discoveries included Ontario, Key West, Boss, Fountain, and Gold Flake.

The Town of Breckenridge was incorporated on March 3, 1880.
Geography
According to the United States Census Bureau, the town has a total area of , all land. At the elevation of the weather station, the climate could be described as a subalpine climate (Köppen Dfc) since summer means are above in spite of the very cool mornings. Winter lows are quite severe, but afternoons averaging around the freezing mark somewhat moderate mean temperatures.
A weather station was run in the town from 1893 to 1913, and from 1948 to the present day. However, temperature measurements are mostly confined to the first period, and the temperature record is thus very sparse. Even so, a temperature of freezing or below was recorded for every single date of the year except July 26. During the winter of 1898–1899, snow was reported to fall for a record 79 consecutive days. Residents tunneled through the snow to navigate Main Street.
