1956 Map of Arlington West

About this map

The Stillaguamish River and its complex network of sloughs, including Cook Slough and South Slough, define this Snohomish County landscape as it appeared in the mid-1950s with late-1960s updates. The topography is dominated by The Island, a large landmass carved by the river's path, while the Northern Pacific railroad corridor serves as the primary industrial spine for the region. To the south, the expansion of Arlington Airport and the emerging hub at Smokey Point indicate the area's transition toward post-war aviation and commerce.
