Preceding Context: Great Falls quickly became a thriving industrial and supply center and, by the early 1900s, was en route to becoming one of Montana's largest cities. The rustic studio of famed Western artist Charles Marion Russell was a popular attraction, as were the famed "Great Falls of the Missouri," after which the city was named. A structure billed as the "world's tallest smokestack" was completed in 1908 by the city's largest employer, the Anaconda Copper Mining Company's smelter, measuring tall. The Big Stack immediately became a landmark for the community. The Big Stack's 'sister' stack in
Succeeding Context: was suffering from cracking and it was decided to remove the support bands from the upper half of the Big Stack and send them to Anaconda. This action proved to be the Big Stack's ultimate demise since the cracks it suffered from rapidly worsened. Citing public safety concerns due to the stack's continual deterioration of its structural integrity it was slated for demolition on September 18, 1982. In an interesting twist of fate the demolition crew failed to accomplish the task on the first try; the two worst cracks in the stack ran from just above ground level to nearly 300 feet up. As the 600 lbs of explosives were set off (which was to create a wedge in the base so it would fall almost vertically into a large trench for the rubble) the cracks 'completed themselves' all the way to the ground -- effectively severing the stack into two-thirds and one-third pieces. Much to the delight of the spectating community, the smaller of the two pieces remained standing, but the failed demolition only solidified the safety issue whereas the community cited the event as the stack's defiance. The demolition team who had planted the charges was recalled and several hours later they returned and finished the demolition, after packing another 400 lbs of explosives into the smaller wedge.
