Oregon is 295 miles (475 km) north to south at longest distance, and 395 miles (636 km) east to west. With an area of 98,381 square miles (254,810 km2), Oregon is slightly larger than the United Kingdom. It is the ninth largest state in the United States.[1] Oregon's highest point is the summit of Mount Hood, at 11,249 feet (3,429 m), and its lowest point is the sea level of the Pacific Ocean along the Oregon Coast.[2] Oregon's mean elevation is 3,300 feet (1,006 m). Crater Lake National Park, the state's only national park, is the site of the deepest lake in the United States at 1,943 feet (592 m).[3] Oregon claims the D River as the shortest river in the world,[4] though the state of Montana makes the same claim of its Roe River.[5] Oregon is also home to Mill Ends Park (in Portland),[6] the smallest park in the world at 452 square inches (0.29 m2).
Oregon is split into eight geographical regions. In Western Oregon: Oregon Coast (west of the Coast Range), the Willamette Valley, Rogue Valley, Cascade Range and Klamath Mountains; and in Central and Eastern Oregon: the Columbia Plateau, the High Desert, and the Blue Mountains.
Oregon lies in two time zones. Most of Malheur County is in the Mountain Time Zone, while the rest of the state lies in the Pacific Time Zone.
