Clyde Park is a small rural community in Park County, Montana, spanning 79 square miles of agricultural and mountain terrain. The post office maintains 363 PO Boxes for 318 occupied households, creating a 1.14 adoption rate that indicates service extending beyond the immediate town. This is a PO Box Only Zone, meaning there's no alternative mail delivery across the territory.
The community has a typical Montana ranch town character. Rural carrier routes serve scattered properties along roads named for local geography: Brackett Creek Road, Rock Creek Road, Castle Mountain Road, and Lower Cottonwood Road. The town center maintains a numbered grid (1st through 5th Streets, numbered Avenues) with about 120 delivery points on two rural routes.
With a median age of 50.3 years and a population of 729, Clyde Park leans older than Montana's statewide median. The median household income of $60,556 and median home value of $330,600 suggest a mix of working ranches and newer rural residential development. Notably, 27% of workers work from home, likely professionals who've chosen this area for its rural character while maintaining remote careers.
The 40 business establishments employ 142 people, indicating most residents either commute elsewhere or work from home. The area's limited street delivery infrastructure and reliance on PO Boxes reflects both the dispersed settlement pattern typical of rural Montana and the practical realities of mail delivery across mountain and ranch country where homes sit far from maintained roads.
Mix of numbered grid streets in town center and rural roads named for creeks and mountains.
