1985 Map of Sedro-Woolley South

About this map

The Skagit River meanders through the northern portion of this quadrangle, shaping the broad Skagit Valley where Skiyou Island and Ross Island break the water's flow. Along its banks, the industrial and residential outskirts of Sedro-Woolley represent the regional hub of the mid-1980s. To the south, the landscape transitions from the river's floodplain into the timbered slopes of the Cultus Mountains, dominated by the summit of Cultus Mtn. This area is characterized by its vital water systems and lakeside settlements, including the communities surrounding Big Lake and Clear Lake. The presence of several utility corridors, such as a Double Wood Pole Line and Pipe Line, indicates the infrastructure supporting these foothill towns. Local industry is visible in the form of a Quarry and Gravel Pit, while the Judy Reservoir sits tucked within the higher elevations east of the main valley settlements.
