Eastern Oregon is the eastern part of the U.S. state of Oregon. It is not an officially recognized geographic entity, thus the boundaries of the region vary according to context. It is sometimes understood to include only the eight easternmost counties in the state; in other contexts, it includes the entire area east of the Cascade Range. Cities in the broadest definition include Baker City, Bend, Burns, Hermiston, John Day, Klamath Falls, La Grande, Ontario, and The Dalles. Major industries include timber, agriculture, and tourism, with the main transportation corridors consisting of I-84, U.S. Route 395, U.S. Route 97, U.S. Route 26, U.S. Route 30, and U.S. Route 20. Compared to the climate of Western Oregon, the climate of Eastern Oregon is a drier continental climate, with much greater seasonal variations in temperature. Unlike the Willamette Valley, Eastern Oregon receives a significant amount of snow in the winter. Some parts of Eastern Oregon receive fewer than of rain yearly, classifying them as deserts. This desert climate is in part due to a rain shadow effect caused by the Cascade Range. Pine and juniper forests cover 35% of Eastern Oregon, much in the mountains that include the Blue Mountains, Strawberry Mountains, Wallowa Mountains, Trout Creek Mountains, Ochoco Mountains, and Steens Mountain. Volcanic basalt flows from the Columbia River Basalt Group covered large sections of Eastern Oregon 6 to 17 million years ago. Other landforms include the Alvord Desert, Owyhee Desert, Warner Valley, Deschutes River, Owyhee River, Grande Ronde River, Joseph Canyon, The Honeycombs, and Malheur Butte. == Geography == According to the Eastern Oregon Visitor's Association, Eastern Oregon includes only the following counties: Morrow, Umatilla, Union, Wallowa, Grant, Baker, Harney, and Malheur.〔(【引用サイトリンク】url = http://www.eova.com/index.html )〕 Other definitions of the region are sometimes more restrictive,〔(【引用サイトリンク】url = http://www.frommers.com/images/destinations/maps/jpg/2780_easternoregon.jpg )〕 others include the base eight counties listed above plus several adjacent counties,〔(Explore Eastern Oregon. ) Oregon Parks and Recreation Department. Retrieved on October 26, 2007.〕〔(Eastern Oregon. ) Guide to Oregon. Retrieved on October 26, 2007.〕 while some definitions include the entire area east of the Cascade Range;〔(Are Introduced Plants Common in Eastern Oregon Forests? ) United States Forest Service. Retrieved on October 26, 2007.〕 this meaning would also include Sherman, Crook, Deschutes, Gilliam, Jefferson, Klamath, Lake, Wasco, and Wheeler counties. The extreme eastern section of Oregon in the Snake River Valley, including Ontario, is part of the Treasure Valley, which extends east to Boise, Idaho; unlike the rest of the state, that section lies within the Mountain Time Zone. Sacajawea Peak is the region's highest mountain. ==Politics== Although Oregon as a whole is generally considered a Blue State, Eastern Oregon is far more conservative. In the 2012 Presidential Election, Mitt Romney received at least 60% of the vote in every county in Eastern Oregon.〔(【引用サイトリンク】url=http://uselectionatlas.org/RESULTS/state.php?f=0&fips=41&year=2012 )〕 The political divide between the eastern and western parts of the state have led some residents of Eastern Oregon to feel that the state of Oregon, with the majority of its population and political control based in the western part of the state, has neglected the eastern part of the state, preventing it from developing along with the western part. A movement to have Eastern Oregon secede and join the United States as a 51st state was underway in 2008. This movement is similar to other Northwest secession proposals such as Jefferson, Lincoln, and Cascadia. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eastern Oregon」の詳細全文を読む スポンサード リンク
