Alma sits at 10,578 feet elevation in Park County, Colorado, making it one of America's highest incorporated towns. This former mining community spans 58 square miles of Rocky Mountain terrain, where 927 year-round residents share space with seasonal visitors and second homeowners. Street names preserve the area's mining past: Gold Run Road, Mine Dump Road, Pyrite Place, Nugget Lane, and Bauxite Lane reference the gold and silver strikes that built the town in the 1870s.
This is a PO Box Only Zone. No street delivery exists across the territory. The Alma post office maintains 426 PO Boxes for 454 occupied homes, a 93.8% adoption rate that shows near-universal reliance. Rural carrier routes serve scattered properties along county roads, but most residents pick up their mail at the post office.
Of the 894 total housing units, 361 sit vacant for seasonal or recreational use. That's 40% vacancy. Alma functions as a year-round mountain community and part-time vacation destination. Median home values reach $572,500, well above typical small-town Colorado levels. The median age of 42 years indicates an established population, neither college-aged nor retirement-dominant.
The workforce patterns tell a mountain story. Among workers, 34.3% work from home (121 people), likely remote professionals who chose mountain living. Another 372 work in transportation, warehousing, and utilities. That's unusually high for a town this size and probably includes ski area workers, highway maintenance crews, and logistics for surrounding communities. Public transit sees significant use (108 commuters), suggesting connections to nearby ski resorts and larger towns.
Education levels run high: 65.6% of adults hold bachelor's degrees or higher, compared to national averages around 33%. These aren't traditional rural demographics. This is a mountain community that attracts educated professionals seeking altitude and isolation.
Alma's street names show quirky mountain character alongside mining heritage. There's Dead Toad Road, Koochie Koochie Road, No Name Lane, and Lazy Rex Road mixed with Ice Axe Court and Adventure Road. County roads numbered 1 through 665 form the addressing backbone, typical of rural Colorado delivery patterns.
