North Valley & Jefferson County

The communities north of Idaho Falls along I-15 and US-20, spanning northern Bonneville County and Jefferson County. Anchored by Rigby (pop. ~6,000) — the Jefferson County seat and self-proclaimed 'Birthplace of Television' — this region includes small towns surrounded by irrigated farmland on the Snake River Plain. Iona and Ucon serve as bedroom communities for Idaho Falls commuters, while Menan and Roberts retain their agricultural character.
