Oregon is located in the Pacific Northwest region of the United States, bordered by the Pacific Ocean to the west, California and Nevada to the south, Idaho and the Snake River to the east, and Washington and the Columbia River to the north. It is the ninth largest by area and the 23rd most populated state. The Willamette Valley area in Western Oregon is the most densely populated and contains eight of the ten most populated cities. Salem is the capital, and Portland is the largest city in the state. Other large cities include Eugene, Gresham, Hillsboro, Beaverton, Bend, Medford, Springfield and Corvallis. There are still nine federally recognized Native American tribes in the state. Oregon has a diverse landscape, with the windy Pacific coastline, the Cascade Range dotted with volcanoes, abundance bodies of water west of the Cascades, dense evergreen and deciduous forests at lower elevations, and high desert covering much of the eastern part all the way to the Great Basin. Mount Hood is the state's highest point, and Crater Lake is the deepest lake in the country.
