Thornton and surrounding Archer and Lyman. Location Thornton lies approximately seven miles south of Rexburg, Idaho and is bordered on the south by the Lorenzo Bridge, which crosses over the South Fork of the Snake River. Visible in the near west horizon are the Menan Buttes. Thornton lies on the Oregon Short Line Railroad and was built around what is now a remnant of U.S. Highway 191. This short segment of the original highway terminates within Thornton, at an old cement bridge. Since its original establishment, Thornton has been bisected by the construction of US Highway 20. The larger portion lies south of the highway- the northern portion has been nearly completely eliminated by the construction of the highway. The Archer-Lyman highway begins to the north and east of Thornton and meanders south and then east towards Ririe, Idaho. The old brick Thornton Hotel is no longer in operation and has been abandoned due to disrepair. The legal description of Thornton is "NE 4 NE 4 of Sec. 222, and of SW 4 SW 4 of Sec. 14 and of SE 4 SE 4 of sec 15 all in TS 5 N R 39 E.B.M." Attractions, Landmarks Within Thornton next to the remaining Thornton Merc is an old trailer park which now accommodates both campers and longer-term residents, many of whom are migrant workers who labor in the nearby potato warehouses. Another RV Park lies south across the old concrete bridge nearer to the Snake River South Fork. A bed and breakfast appears on the map here as the Sheffield House The Thornton Shell gas station and convenience store lies between Highway 20 and the railroad and used to be known as the Mini Mart. Behind the Shell station is the old grain elevator which now advertises the gas station. Also marooned between the two highways is an older home which was once owned by the Keith Wilcox family in the mid 1900s, which has been stranded now due to the removal of a portion of South 3300 West. A nearby potato warehouse owned by Keith and his sons is no longer in operation, and is vacant except for individuals who have taken residency in the office space. Part of a community church still stands in Thornton, though it is no longer in use. There is a quiet RV park across from the potato warehouse called Thompson RV Park. It
