About this map

The North Fork Stillaguamish River cuts a prominent path through this Snohomish County landscape, anchoring the small valley settlements of Oso, Cicero, and Halterman. The terrain is defined by the steep rise of Frailey Mountain to the north and Ebey Hill to the south, creating a constrained corridor for transit and industry. Local resource extraction and conservation efforts are evident through landmarks like the Oso Gravel Quarry and the Arlington Hatchery.

Hydrographic features are numerous, from the upland waters of Larch Lake and the expansive Lake Cavanaugh to the complex network of tributaries such as Deer Creek, Brooks Creek, and Fry Creek. The road network, including Deer Creek RD and Oso Loop RD, follows the natural contours of the river valley, illustrating the deep connection between the geography of the Stillaguamish and the local development patterns during the early 21st century.
