CASTLE GATE MINE CASTLE GATE, Utah BACKGROUND The Utah Fuel Company, Utah’s largest coal company at the time, owned the Castle Gate coal mines and company town and store. The Denver and Rio Grande Western Railroad, which hauled the coal, was a major shareholder. The railroad exited bankruptcy in 1923 after having gone bankrupt in 1918 and seized by the federal government during World War I. Denver and Rio Grande Western Railroad Castle Gate Station, 1929

CASTLE GATE MINE CASTLE GATE, Utah Mules & Horses During normal operation, mules & horses pulled coal carts most of the way out of Castle Gate Mine No. 2. A small railroad brought the coal the rest of the way out. Most mules & horses never saw daylight again after entering the mine. There were underground stables. The mules typically died after 3.5 years, vs. 30 - 50 years when free.
CASTLE GATE MINE CASTLE GATE, Utah CANARIES Mines around the world used canaries as carbon monoxide detectors. If levels got too high, the canaries would become distressed and/or pass out. Some mines used rats. Some canaries recovered after re-surfacing. Some mines used oxygen tank devices to resuscitate their canaries.
CASTLE GATE MINE DISASTER CASTLE GATE, Utah MULES, HORSES, & MEN DIED TOGETHER Some papers reported on the mules and horses killed in the disaster. One paper framed the horses’ deaths in terms of their monetary value and the cost to train them. The same article noted that the “horses and their drivers...died side by side.” And, that “some of the drivers would be found under the carcasses of the horses.”
CASTLE GATE MINE DISASTER CASTLE GATE, Utah MULES, HORSES, & MEN DIED TOGETHER The recovery teams left the mules’ and horses’ bodies where they died. They used chemicals to dry out the flesh in order to make it easier to remove them later.
CASTLE GATE MINE DISASTER CASTLE GATE, Utah CANARIES Since any canaries in the mine at the time of the explosion would have been killed, rescue & recovery workers commandeered 20 local pet canaries and shipped in 30 more to detect dangerous gas levels. About 16 out of 50 canaries died in the rescue and recovery efforts. One paper claimed the canaries “gave up” their lives to rescue the workers. We still see similar doublespeak regarding animals killed while “working” for human benefit. It provides comfort to the humans, but certainly not to the animals.
CASTLE GATE MINE DISASTER MEMORIALS The official memorial only honors the human victims. As of yesterday, the disaster’s Wikipedia page only mentioned the human victims. I added the mules, horses, and canaries.

CASTLE GATE MINE 2025 - Still Burning Castle Gate Mine No. 2 caught fire again in 2025. Workers risked their lives sealing the vent with foam. However, the fire still burns underground. The Federal Office of Surface Mining Reclamation and Enforcement plans to investigate the site further in spring 2026.

APPENDIX 1922 COAL STRIKE Two years before the explosion, Castle Gate coal miners went on strike during a nationwide coal strike organized by the United Mine Workers union after failed contract re-negotiations. The nationwide coal strike lasted from Apr 1 - Sep 11, 1922. Conservative papers blamed the strikes on “outside agitators.” Railroad workers launched a nationwide solidarity strike to support the miners.
CASTLE GATE MINE 1922 COAL STRIKE Tensions between the company, its mine police, strikers, and scabs resulted in a fatal shootout. The miners shot a company mine guard’s horse in the melee. The company and its mine guards accused the strikers of firing first. The miners accused the coal guards and strikebreakers of firing first. Papers used xenophobia to discredit strikers. In addition to immigrant miners, the industry imported canaries. Utah Governor Charles R. Mabey declared martial law and deployed the National Guard.
CASTLE GATE MINE 1922 COAL STRIKE On Sep 2, 1922, even the scabs joined the strike The same day, the national United Mine Workers agreed to end the strike with a new contract re-establishing the previous contract’s terms. The Castle Gate miners demanded the same deal.
CASTLE GATE MINE DISASTER 1922 COAL STRIKE The 1922 strike succeeded in maintaining wages. However, it also maintained existing safety protocols. These proved insufficient two years later when Castle Gate Mine No. 2 exploded on Mar 8, 1922.
APPENDIX In 1918, the state of Utah used prison laborers to build the roads around the mine.
