Nondalton sits on the shore of Lake Clark in southwestern Alaska's Lake and Peninsula Borough, serving a predominantly Alaska Native community across 2,749 square miles of remote wilderness. Of the 122 residents, 102 are Native American (84%), making this one of Alaska's Alaska Native villages with PO Box-only mail service. The post office provides the only mail access across this vast territory, where no alternative delivery exists.
This is a PO Box Only Zone. The post office maintains 48 PO Boxes for 48 occupied households, a perfect 1:1 match that shows universal reliance on box service. There's minimal street addressing infrastructure. Only Main Street appears in postal records, and a single rural route serves the handful of locations with street delivery. General Delivery is available for those without boxes.
The community's housing stock tells the story of Alaska's seasonal patterns. Of 126 total housing units, 78 sit vacant, with 45 classified as seasonal or recreational use. That's 62% overall vacancy and 36% seasonal vacancy. These numbers point to hunting and fishing cabins, seasonal workers' quarters, and the rhythms of subsistence living in rural Alaska.
With a median household income of $51,667 and median home values of $137,500, Nondalton's economy centers on subsistence activities, seasonal work, and public employment. Census data shows 20 workers in public administration, the dominant employment sector in this village of 122 people. Educational attainment is low, with just 14.5% of adults holding bachelor's degrees. The median age of 36 years indicates a younger population structure than most rural Alaska communities.
Nondalton's location near Lake Clark National Park and Preserve puts it at the edge of one of Alaska's most spectacular wilderness areas. The seasonal housing vacancy reflects the area's role in tourism, sport fishing, and hunting. But for year-round residents, the post office is an essential lifeline for mail, packages, government documents, and connection to the outside world across thousands of square miles where roads don't reach.
With only Main Street in postal records, this village has minimal formal street addressing typical of remote Alaska Native communities.
ZIP Code 99640 has 122 residents and 48 households (average 2.54 persons per household). The median age is 36.0 years, about the same as the state (35.6) and slightly younger than the nation (38.8).
