1956 Map of Arlington East

About this map

The North Fork Stillaguamish River and South Fork Stillaguamish River converge just east of Arlington, creating a landscape defined by fertile valley floors and the rising slopes of Ebey Hill. This 1950s survey documents the community of Trafton to the north and the development across Arlington Heights, while purple-tinted revisions from 1968 indicate the expanding urban footprint of the era. The infrastructure of the period is prominent, with a pipeline corridor cutting through Sisco Heights and multiple gaging stations monitoring the river forks.
