GEO 220 - Pacific Northwest Geology

5 Credits
To give the student an understanding of the geologic history of the Pacific Northwest by including the influence of plate tectonics upon the mountain building and microcontinent plate collisions; includes several overnight field trips which gives geologic field evidence emphasizing physical and biological records of rock strata and structure.

Course Outline
  • The geologic framework of Cordilleran landscapes
  • Columbia and the Rocky Mountains
  • North Cascades
  • Central and Western British Columbia
  • San Juan Islands
  • Coast Range Province
  • Cascade Range of Oregon and Southern Washington
  • Cascade volcanoes
  • Blue Mountains Province
  • Southeastern Oregon
  • Volcanic highland
  • Snake River Country
  • Columbia Plateau
  • Puget-Willamette lowlands 
  • The geologic history of these diverse regions are correlated to develop an integrated history of the Pacific Northwest through the theme of plate tectonics.

Student Learning Outcomes
Student will be able to explain how plate tectonics produced a mosaic of microcontinents through plate collisions.

Student will apply knowledge of concepts and processes learned in a classroom to the interpretation of outcrops and fieldwork.

Student will identify common rocks and rock-forming minerals in various Pacific Northwest field settings.

Student will create  geologically reasonable hypotheses based on learned knowledge to explain observations of rocks and features.

Student will present a relevant scientific interpretation of key field data from select field sites in the Pacific Northwest.

Student will sketch and describe their observations in the field to recognize characteristic rock and sediment units and interpret those observations to create hypotheses about the geologic history of the Pacific Northwest.

Student will practice safety in geologic fieldwork by fully participating, following safety protocols, paying attention, and following directions of trip leader(s) at all times.

Student will be able to discuss the general geologic history for the major geologic regions of the Pacific Northwest.
