Thistle is a ghost town in Utah County, Utah, United States.
During the era of steam locomotives, the town's primary industry was servicing trains for the Denver and Rio Grande Western Railroad.
In April 1983, a massive landslide dammed the Spanish Fork River.
Residents were evacuated as nearly 65,000 acre feet (80,000,000) of water backed up, flooding the town. Thistle was destroyed; only a few structures were left partially standing.
The landslide resulted in the first presidentially declared disaster area in Utah.
