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.
