Winter Quarters is a ghost town in Carbon County, Utah, United States. Coal was discovered in the area in 1875, and later that year, the Pleasant Valley Coal Company began coal mining operations. A group of coal miners were delayed during an early winter storm in 1877, which led to the town's name of Winter Quarters. On May 1, 1900, an explosion in the Winter Quarters Number Four mine killed 200 miners. Despite the mine explosion, the coal mining operations remained active until 1922, when the opening of a new mine in Castle Gate caused many people to relocate there.
