Avery is a small unincorporated community nestled in the St. Joe River Valley in Shoshone County, Idaho, United States. Avery is located in the middle of the St. Joe District of the Idaho Panhandle National Forest. Avery is a popular tourist attraction in northern Idaho for its beautiful wilderness and outdoor recreation.
This climatic region is typified by large seasonal temperature differences, with warm to hot (and often humid) summers and cold (sometimes severely cold) winters. According to the Köppen Climate Classification system, Avery has a humid continental climate, abbreviated "Dfb" on climate maps.
Avery has a population of 25 permanent residents. The temporary population is higher in the summer though due to seasonal workers for the United States Forest Service and the many summer homes in Avery and along the St. Joe River.
The town was from the years 1909 to 1980 a division point on the Milwaukee Road railroad's "Pacific Extension". It was also once the western terminus for the easternmost of two electrified mountain sections on the route. The other ran from Othello, Washington, through the Cascade Mountains to the Puget Sound. Electric operations ran from 1914–74 on this section to Harlowton, Montana. Trains stopped at the Avery Depot, now listed on the National Register of Historic Places. Here, steam or diesel locomotives were changed or hooked up to electric locomotives.
