Anaconda Smoke Stack State Park
The 585-foot tall Anaconda Smoke Stack was built in 1918. It is alleged to be the tallest masonry structure in the world.
Backstory and Context
The Anaconda Copper Mining Company was founded by Marcus Daly in 1881. Born in Ireland in 1841, Daly arrived in New York City in 1856 when he was 15. In 1861 he eventually made his way to San Francisco where one of his sisters had been living. He found work as a ranch hand, railroad worker, and logger before becoming a miner in the early 1860s. Daly rose up in the ranks and became a foreman for a mining company in Utah. The company sent him to investigate a mine called the Alice Mine, which the company bought; Daly also bought a share of the mine as well. He sold his share of that mine 1881 and bought Anaconda silver mining claim. With financial assistance from other investors, including William Randolph Hearst, Daly developed the mine and found a large deposit of copper there—one of the largest found up to that point. As as result, Daly became rich and one of the "Copper Kings" of the late 19th century. The company would grow to become the largest copper mining company in the world by 1915.
Daly built a smelter to process ore from the mine, which was near Butte, and founded the city of Anaconda in 1883. The first smoke stack was 225 feet high. This was not high enough; the smoke from the stack polluted arsenic, dust, and sulphur oxides, all of which affected the health of the local population, farm animals, and reduced crop yields. A taller, 300-foot smoke stack was built in 1903 but this, too, was not high enough. It took until 1918 for the current smoke stack to be built. However, the stack emitted even more pollution and this continued for several decades until the smelter closed in 1980. It was added to the National Register of Historic Places 1987.
