2014 Map of Oso

About this map

The North Fork Stillaguamish River defines the southern landscape of this Snohomish County survey, flowing past the communities of Oso and Halterman. The northern terrain is dominated by the waters of Lake Cavanaugh, where a network of roads including N Shore Dr and S Shore Dr service the residential development along its banks. The map provides a look at the boundary between Skagit and Snohomish counties, tracing the mountainous transition from Frailey Mtn in the west toward high-elevation water bodies like Larch Lake in the east.
