The geologic setting of the Nehalem watershed is strongly influenced by the active tectonic associated with the Cascadia Subduction Zone and Oregon Coast Range. Bedrock stratigraphy includes several formations ranging in age from Eocene up to middle Miocene, in addition to Quaternary terrace gravel and alluvium. Topographic lineaments in the Nehalem basin are associated with known fold structures, faults, formation contacts and/or resistant strata. Surficial geology is characterized by parent rock and soils formed through volcanic and depositional processes.
