Aldridge is a ghost town in Park County, Montana, United States.

Aldridge is located two miles (3.2 km) north of the northern entrance to Yellowstone National Park.

[2] According to an insert in the Park County News, the story of Aldridge begins when Major Horr discovered five coal veins on a side hill near Cinnabar in 1872.

In November, 200 men marched from the mines at Lake to the Montana Coal Company office in Horr to demand higher wages.

All the coal was mined on the 3,000 acres (1,214.1 hectares) of land surrounding Aldridge, but in August 1904 the miners went on strike.

With no mines operating in Electric, its economy survived by transporting iron ore to the smelters from its railhead.

Local newspapers predicted that Aldridge would become one of the most important coal and iron ore mining camps in the country.

[2] Although Aldridge had a bright future, the Montana Coal Company defaulted in payments of bonds in 1910.

[3] The bondholders won the suit and the Montana Coal and Coke Company was sentenced to pay over 100,000 dollars.
