Chapter 17: Pacific Northwest

The Pacific Northwest is a region of western North America bordered by the Pacific Ocean and the Rocky Mountains. Although there have been disagreements over the actual definition of the exact boundaries that make up the Pacific Northwest. The Northwest is highly geologically active with seven active volcanoes and geological faults. Active volcanoes include Mount Garibaldi, Mount Baker, Mount Rainier, Mount Saint Helens, Mount Hood, Mount Jefferson, and Mount Shasta. Mount Saint Helens last erupted in 1980. Unlike The Pacific Northwest, Los Angeles is not home to any active volcanoes but is located just east of the San Andreas Fault.
