Crater Lake National Park … US
Crater Lake National Park (Crater Lake) is one of 58 national parks in the United States. Located high in the Cascade Range (Cascade Range-the highest peak of the mountain is Mount Rainier at an altitude of 4,392 meters) in the southwest US state of Oregon. It is surrounded by huge vertical cliffs and located in the crater of an extinct volcano.
When you say “southwest” do you mean the southwest of the state of Oregon, because Oregon is surely northwest rather than southwest in terms of American geography?
