Welcome to the Newcastle (Washington) Historical Society




Cougar Mountain Regional Wildland Park and Coal Creek Park together encompass the heart of an old 19th century coal district. Many people driving past on a daily commute may not know they are near the site of the old Newcastle coal mines. Coal miners and prospectors worked these mines from 1863 to 1963, removing nearly 1 million tons of coal, as well as 4 million tons of waste rock.

The towns of Newcastle and Coal Creek, separated by one and a half miles of thick forest, grew up around the mines, and in the 1880s they comprised the second largest community in King County. As the county’s earliest sizable industry, Newcastle coal mining caused Seattle to grow from a small village in the 1860s to a major port city in the 1880s.

In 1863 coal attracted investors from California and the East Coast, who put the miners to work digging surface deposits and excavating shallow tunnels. Originally workers bagged the coal and took it to Lake Washington to barges. By 1872 coal was dumped into cars, pulled by horses to Lake Washington, barged across the lake, pulled to Lake Union, barged again, then pulled to coal bunkers on Elliott Bay. In 1870 the Seattle and Walla Walla Railroad laid tracks to Newcastle. The train took coal to Seattle quickly, which in turn made the railroad profitable.

With explosives and handpicks Newcastle miners created huge, underground caverns ventilated by air shafts. Tram cars pulled by mules hauled coal out, where workers sorted out the waste rock. Miners showered at a company wash house–which was so much easier than bathing at home, that their wives demanded a “ladies night” at the showers.

Coal dust in the dry mines–potentially explosive–was the biggest danger. The mines were continuously sprayed with water, but an 1894 explosion killed four miners. Two months later, fire threatened the area from underground. Coal Creek was diverted in the mine to put out the fire, leaving smoke hanging over the community for months.

Coal production stayed high through World War I. However, immediately following the war, strikes were common. A fire destroyed part of the mining equipment, and the mining operations closed. Independent miners continued to mine until the 1960s, often with a danger of cave-ins from working too near the surface. Today the earth occasionally slides into a forgotten tunnel, and locals sometimes think the smoke clinging to the valley on clear days comes from fires still smoldering in the abandoned mines. Remnants of mine shafts, concrete foundations and tailings dotting the parks are disappearing into the forest of Cougar Mountain.

    Information discovered at Tacoma Cemetery suggests a relative “Teresa Mullarkey” died at age 11 months in July 1885. At that time her family lived in Newcastle where her father John D Mullarkey worked in the coal mines. I think it possible she might be buried in the Newcastle Cemetery.

    Can you tell me if internment records exist ?

    Can you please verify the 1870 date in the third paragraph? If the tracks were laid in 1870, why would they be barging the coal in 1872? I’m wondering if that’s a typo. Thanks!
