Preston is a city in Franklin County, Idaho, United States.The Bear River Massacre occurred in 1863 at a point a few miles northwest of Preston.The Bear River Massacre Site is a National Historic Landmark.In 1866, Latter-day Saint pioneers arrived in the northern end of the Cache Valley, stretching across southeastern Idaho and northeastern Utah.They founded a community in that location and named it Worm Creek, but in 1881 changed it to Preston because leaders of the Church of Jesus Christ of Latter-day Saints (LDS Church) in Salt Lake City objected to the name "Worm Creek" being part of any church congregation's name.[8][9] It was not until the 1880s while William C. Parkinson was serving as the bishop of the Preston LDS Ward that a regular townsite was laid out.[11] Nearby is the Cub River Canyon, which is a popular recreation area.For several years the city held a "Napoleon Dynamite Festival" in the summer.[18] Each year Preston holds the "Idaho Festival of Lights",[19] which starts the day after Thanksgiving and goes until December 31.
