Living in Butte County
High-desert value in the Lost River Valley — Arco, the first city lit by atomic power, gateway to Craters of the Moon and to Idaho’s tallest peaks in the Lost River Range.
Butte County real estate centers on Arco, Moore and Howe in the high-desert valleys of the Big Lost and Little Lost rivers. Arco, the county seat, was the first community in the world lit by nuclear-generated electricity, and the county is home to the visitor center of Craters of the Moon National Monument. Buyers come for affordable rural property, open space and some of East Idaho's most dramatic scenery.
Butte County Economy & Jobs
Much of the eastern part of Butte County is occupied by Idaho National Laboratory, which is an important employer for the area. Ranching and irrigated agriculture in the Big Lost River Valley, along with tourism tied to Craters of the Moon, support the rest of the local economy.
History of Butte County
The first settlement, near present-day Arco, began in 1878 at a Lost River crossing, and the town took the name Arco when its post office opened in 1879. Construction of the railroad from Blackfoot to Mackay led Arco to move to its present site in 1901. Butte County was created on February 6, 1917, from parts of Bingham, Blaine and Jefferson counties, and named for the three volcanic buttes, Big Southern, Middle and East Butte, that guided trappers and pioneers across the plain. In 1955 Arco became the first town lit by nuclear power, using electricity from a reactor at what is now Idaho National Laboratory.

Land, Acreage & Horse Property in Butte County
Butte County land ranges from irrigated farm and ranch property in the Big Lost River Valley to dry high-desert parcels. Water is the key question: both the Big Lost and Little Lost rivers sink into the Snake River Plain aquifer within the county, so well depth and water rights matter on every purchase. Valorie's List only labels horse property when the MLS reports livestock permitted.
