  • With 181 seasonal homes out of 284 total units, 57% of housing is used for vacation rather than year-round residence
  • The post office maintains 160 PO Boxes for 103 occupied households, serving both residents and seasonal property owners across the rural area
  • Median age of 55.3 years and 73% of adults with bachelor's degrees indicate an educated, older population
  • Street names like 13th Lake Road, Barton Mines Road, and Garnet Hill Road reference the area's mining history and Adirondack geography

A Seasonal Community

North River sits in the southern Adirondacks of Warren County, where seasonal residents far outnumber year-round inhabitants. Of the 284 housing units scattered across this 66-square-mile territory, only 103 are occupied year-round. The remaining 181 units (57% of all homes) are used seasonally, mostly as vacation properties for families drawn to the region's lakes, mountains, and forests.

Why PO Boxes Are the Only Option

This is a PO Box Only Zone. There's no alternative mail delivery across this rural expanse. The North River post office maintains 160 PO Boxes for 103 occupied households, resulting in an adoption rate of 1.55. That means the post office serves not just local residents but also seasonal homeowners, nearby camps, and scattered properties throughout the surrounding area. With only two rural carrier routes covering 66 square miles, PO Boxes provide reliable mail access where street delivery isn't feasible.

Demographics of a Quiet Retreat

Median age here is 55.3 years, well above the national average. This isn't a community of young families. It's retirees, second-homeowners, and established residents who value the quiet and remoteness. Despite the rural setting, 73% of adults hold bachelor's degrees or higher, one of the highest education rates for any PO Box ZIP in New York. Median home values of $223,300 and household incomes around $58,714 indicate comfortable middle-class to upper-middle-class demographics.

The Adirondack Character

Street names tell the story of this place. State Route 28 runs through the area as the main corridor. Roads like 13th Lake Road, Barton Mines Road, and Garnet Hill Road reference local geography and history. Names like Whispering Pines Way, Lakeview Lane, and Knotty Pine Lodge Road suggest the vacation character. This is mining country (the Barton Garnet Mine operates nearby) and lake country, with modest camps and seasonal homes tucked into the woods.
