When the final brick was mortared into place on November 30, 1918, this smokestack stood 585.56 feet in height, the tallest in the world at the time. It narrowly escaped demolition with the rest of the Anaconda Smelter in 1980.

When the Anaconda Smelter shut down, then was demolished by its owners, a group named "Anacondans to Preserve the Stack" was formed. Largely through their efforts the stack was spared to stand as a monument to the industry that gave the City of Anaconda life and to all the workers who toiled beneath the stack at that smelter.

The Silver State Post, on November 2, 2011, published an article on the Anaconda Smokestack, outlining a bit of its history and the story of its rescue from destruction. The story, entitled "A historic landmark with a tall tale", appeared on page 11 of that issue. Distribution and reproduction of archived articles at the Silver State Post website is prohibited so, instead, I've provided the story of the smokestack, from a plaque at Smokestack Park, below and a link to The Story on the Silver State Post's website.

During the early years of smelting in Anaconda, each of the many furnaces at the Old Works required its own stack. Later the individual stacks were connected through flues to a large central stack.

When constructed In 1902, he first Washoe Smelter stack stood 285 feet high. As the production capacity of the smelter grew, the decision was made to design and construct one enormous stack to handle the large volumes of flue gas. In May 1918, the 30-foot high octagonal base for the "Big Stack" was completed. It was comprised of 20,891 sacks of cement, 50 railroad cars of sand, and 118 railroad cars of crushed rock. The Washoe Smelter stack was a colossal construction project that was completed in an extremely short time. Construction took 142 actual working days (8-hour shifts), with an average of 12 bricklayers per shift. On May 23, 1918, the first block was set in place and the last block was set in place a little over six months later on November 30, 1918.

From the 30-foot base (elevation 5,754 feet), the stack rises to 585 feet and is constructed of 2,464,652 locally-manufactured tile blocks, the equivalent of 6,672,214 ordinary bricks. Elevation at the top of the stack is 6,339 feet. An enormous amount of material went into the mortar necessary to construct the stack: 41,350 sacks of cement, 77 railroad cars of sand (50 tons per car), and 37 railroad cars of fire clay. Over 300,000 feet of lumber were used in the stack's construction. By May 5, 1919, the flue and stack were placed into operation, and the first smoke from the Washoe Smelter emerged from the stack.
