Oregon is a state in the Pacific Northwest region of the United States. It is located on the Pacific coast, with Washington to the north, California to the south, Nevada on the southeast and Idaho to the east. Salem is the state's capital and third-most-populous city; Portland is the most populous. Oregon contains a diverse landscape including the windswept Pacific coastline, the volcanoes of the rugged and glaciated Cascade Mountain Range, many waterfalls (including Multnomah Falls), dense evergreen forests, and high desert across much of the eastern portion of the state, extending into the Great Basin. The tall Douglas firs and redwoods along the rainy Western Oregon coast contrast with the lower density and fire prone pine tree and juniper forests covering portions of the eastern half of the state. Stretching east from Central Oregon, the state also includes semi-arid shrublands, prairies, deserts, steppes, and meadows. Mount Hood is the highest point in the state at 11,249 feet (3,429 m). Crater Lake National Park is the only national park in Oregon.
