Thistle, Utah

One of the more well known ghost towns of Utah, Thistle is one that happened relatively recently.  The town stood for almost exactly 100 years before being completely flooded because of massive landslides.

Founded by westerners in 1883, the town of thistle was always a small town, but saw a small boom because of it's ability to be a service station for steam trains. As with other steam train boom towns, with the advent of diesel locomotives, the town began to decline afterwards and unfortunately met it's ultimate fate in April of 1983.

The landslide was one of the worst in the USA and was considered to be the costliest in US history to this day. It was also the first time the President officially declared a disaster area in the state of Utah. Both existing railways and highways leading to the town were rendered instantly useless, and new railways and roads were constructed to bypass the disaster area which had cut off the primary access to the eastern portion of the state.

Ultimately, after recovery efforts, the abandoned town was a minor tourist attraction for being a unique example of a modern ghost town partially submerged in the bog that was left over after the disaster. However, that isn't the end of the bad luck for the town, as in 2018 there was a wildfire that affected the area and it destroyed much of what was left of the town's remains, almost erasing it from existence.
