Dumont sits in the mountains of Clear Creek County, Colorado, 14.81 square miles of steep terrain at 9,000 feet elevation. This is a PO Box Only Zone. No street delivery exists across the entire territory. The Dumont post office maintains 282 PO Boxes for 227 households, serving not just local residents but also people from surrounding mountain areas without postal service.
This isn't a new community. Of the 305 housing units, 257 were built before 1939 (84%). Street names like Silver Lakes Drive and Silver City Road point to Colorado's mining past. Today it's a quiet mountain community where nearly 40% of workers (29 of 73) work from home. Median household income is $59,402 with median home values around $370,900.
About 19% of homes (58 of 305) are used seasonally or occasionally. With a median age of 45.5 years and a population of 541, this is a small permanent community supplemented by part-time mountain residents. Rural carrier routes handle most delivery (123 records), with highway contract routes (3 records) covering remote corridors.
Mail delivery here works through one rural route and one highway contract route. The high number of county roads (County Road 308, 312, 260, 261) and nature-themed streets (Mill Creek Road, Picture Mountain Way, Wild Wagoner Trail) show the spread-out mountain character. Business activity is limited: 21 establishments employing 151 people.
All mail must be addressed to a PO Box:
