About this map

The North Fork Stillaguamish River snakes through the valley at the foot of Frailey Mountain, defining the settlement patterns of late 20th-century Snohomish County. Small communities like Oso and Cicero are centered along the river and State Route 530, while the northern portion of the map is dominated by the steep slopes of the Skagit Co Snohomish Co border.

Water management and natural resources are evident throughout the landscape, from the Fish Hatchery near the river to the Boat Ramp on the southern shore of Lake Cavanaugh. Further into the upland terrain, a Quarry and smaller water bodies like Larch Lake and Cicero Pond provide a glimpse into the localized industries and drainage systems that shaped this corner of Washington before more modern developments altered the rural character of the Stillaguamish valley.
