Bridge Creek (John Day River Tributary)
Bridge Creek is a tributary of the John Day River in the U.S. state of Oregon. Part of the drainage basin of the Columbia River, its watershed covers in Wheeler County. From its headwaters in the Ochoco Mountains in central Oregon, the creek flows generally northeast for about from Mount Pisgah in the Bridge Creek Wilderness to the small city of Mitchell on U.S. Route 26. From Mitchell, it flows generally northwest for about , passing through the Painted Hills unit of the John Day Fossil Beds National Monument before meeting the John Day River. Bridge Creek is subject to occasional flash floods, which have affected Mitchell as well as rural areas nearby. Surging water along the creek, which flows parallel to Main Street in Mitchell, caused great damage in 1884 and 1904. A third flood occurred on July 13, 1956, shortly after an intense thunderstorm in the Ochoco Mountains. The creek is usually less than deep in Mitchell during July. Minutes after the thunderstorm, a sudd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

John Day River
The John Day River is a tributary of the Columbia River, approximately long, in northeastern Oregon in the United States. It is known as the Mah-Hah River by the Cayuse people, the original inhabitants of the region. Undammed along its entire length, the river is the fourth longest free-flowing river in the contiguous United States. There is extensive use of its waters for irrigation. Its course furnishes habitat for diverse species, including wild rainbow trout, steelhead and Chinook salmon runs."John Day Subbasin Plan", p. 31 However, the steelhead populations are under federal Endangered Species Act (ESA) protections, and the Chinook salmon have been proposed for such protection. The river was named for John Day (fur trader), John Day, a member of the Astor Expedition, Pacific Fur Company's overland expedition to the mouth of the Columbia River that left Missouri in 1810. Day struggled through eastern Oregon during the winter of 1811–12. While descending the Columbia River ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mitchell, Oregon
Mitchell is a city in Wheeler County, Oregon, United States. The population was 130 at the 2010 census. It was founded in 1873 and was named after John H. Mitchell, a politician. The Painted Hills unit of the John Day Fossil Beds National Monument is about northwest of Mitchell. Mitchell School, a public school with an enrollment of about 70 students, is in Mitchell.

Painted Hills
The Painted Hills is a geologic site in Wheeler County, Oregon that is one of the three units of the John Day Fossil Beds National Monument along with Sheep Rock and Clarno. It totals and is located northwest of Mitchell, Oregon. The Painted Hills are listed as one of the Seven Wonders of Oregon. The layers of color for which the site is named can be traced back to cycling periods of wet and dry climate conditions associated with the transition from the Eocene epoch to the cooler, more temperate Oligocene epoch. The different layers of colors are due to the soil being composed of a combination of mudstone, siltstone, shale and lignite. Geology Formation The Painted Hills began to form 35 million years ago when pumice and ash from volcanic eruptions in the Cascade Mountains traveled 100 miles east and settled over the area. Once there, the ash and other sediments were mixed by natural processes including the flow of water, growth of plants, and the movement of animals. Over ...

John Day Fossil Beds National Monument
John Day Fossil Beds National Monument is a U.S. national monument in Wheeler and Grant counties in east-central Oregon. Located within the John Day River basin and managed by the National Park Service, the park is known for its well-preserved layers of fossil plants and mammals that lived in the region between the late Eocene, about 45 million years ago, and the late Miocene, about 5 million years ago. The monument consists of three geographically separate units: Sheep Rock, Painted Hills, and Clarno. The units cover a total of of semi-desert shrublands, riparian zones, and colorful badlands. About 210,000 people visited the park in 2016 to engage in outdoor recreation or to visit the Thomas Condon Paleontology Center or the James Cant Ranch Historic District. Before the arrival of Euro-Americans in the 19th century, the John Day basin was frequented by Sahaptin people who hunted, fished, and gathered roots and berries in the region.

Flash Flood
A flash flood is a rapid flooding of low-lying areas: washes, rivers, dry lakes and depressions. It may be caused by heavy rain associated with a severe thunderstorm, hurricane, or tropical storm, or by meltwater from ice or snow flowing over ice sheets or snowfields. Flash floods may also occur after the collapse of a natural ice or debris dam, or a human structure such as a man-made dam, as occurred before the Johnstown Flood of 1889. Flash floods are distinguished from regular floods by having a timescale of fewer than six hours between rainfall and the onset of flooding. Flash floods are a significant hazard, causing more fatalities in the U.S. in an average year than lightning, tornadoes, or hurricanes. Flash floods can also deposit large quantities of sediments on floodplains and can be destructive of vegetation cover not adapted to frequent flood conditions. Causes Flash floods most often occur in dry areas that have recently received precipitation, but they may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
