Mount St. Helens National Volcanic Monument is a U.S. National Monument that includes the area around Mount St. Helens in Cowlitz and Skamania Counties, Washington. It was established on August 27, 1982, by U.S. President Ronald Reagan, following the 1980 eruption. The 110,000 acre (445 km2) National Volcanic Monument was set aside for research, recreation, and education. Inside the monument, the environment is left to respond naturally to the disturbance. It was the third national monument to be managed by the U.S. Forest Service.
Fort Rock is a tuff ring located on an ice age lake bed in north Lake County, Oregon, United States. The ring is about 4,460 feet (1,360 m) in diameter and stands about 200 feet (60 m) high above the surrounding plain. Its name is derived from the tall, straight sides that resemble the palisades of a fort. The region of Fort Rock–Christmas Lake Valley basin contains about 40 such tuff rings and maars and is located in the Brothers Fault Zone of central Oregon's Great Basin. William Sullivan, an early settler in the area, named Fort Rock in 1873 while searching for lost cattle.
Powell Butte is an extinct cinder cone butte in Portland, Oregon, United States. It is part of the Boring Lava Field, which includes more than 80 small volcanic edifices and lava flows in the Portland–Vancouver metropolitan area. The region around Powell Butte has a cool climate, and the butte and its surroundings feature meadows, rivers, and mixed forests. Powell Butte hosts the Powell Butte Nature Park, which includes about 612 acres (2.48 km2) of trails for biking, hiking, and horseback riding.
The Klamath Basin is the region in the U.S. states of Oregon and California drained by the Klamath River. It contains most of Klamath County and parts of Lake and Jackson counties in Oregon, and parts of Del Norte, Humboldt, Modoc, Siskiyou, and Trinity counties in California. The 15,751-square-mile (40,790 km2) drainage basin is 35% in Oregon and 65% in California. In Oregon, the watershed typically lies east of the Cascade Range, while California contains most of the river's segment that passes through the mountains. In the Oregon-far northern California segment of the river, the watershed is semi-desert at lower elevations and dry alpine in the upper elevations. In the western part of the basin, in California, however, the climate is more of temperate rainforest, and the Trinity River watershed consists of a more typical alpine climate.
The John Day Formation is a series of rock strata exposed in the Picture Gorge district of the John Day River basin and elsewhere in north-central Oregon in the United States. The Picture Gorge exposure lies east of the Blue Mountain uplift, which cuts southwest–northeast through the Horse Heaven mining district northeast of Madras. Aside from the Picture Gorge district, which defines the type, the formation is visible on the surface in two other areas: another exposure is in the Warm Springs district west of the uplift, between it and the Cascade Range, and the third is along the south side of the Ochoco Mountains. All three exposures, consisting mainly of tuffaceous sediments and pyroclastic rock rich in silica, lie unconformably between the older rocks of the Clarno Formation below and Columbia River basalts above.
The Mascall Formation is a Miocene geologic formation found along the John Day River Valley of Oregon, in the Western United States.
Big Southern Butte is the largest and youngest of three rhyolitic domes formed over a million years near the center of the Eastern Snake River Plain in the U.S. state of Idaho. It is one of the largest volcanic domes on earth. It rises approximately 2500 vertical feet above the lava plain in southern Butte County, east of Craters of the Moon National Monument.
The Bridge Creek Wildlife Area is a wildlife management area located near Ukiah, Oregon, United States. The location was set aside in 1961 as a wintering area for elk.
The E. E. Wilson Wildlife Area is a wildlife management area located near Corvallis, Oregon. The site was named for Eddy Elbridge Wilson, a member of the former Oregon State Game Commission for fourteen years before his death in 1961. Wildlife visible includes blacktail deer, pheasant, and quail.
The Elkhorn Wildlife Area is a wildlife management area located near North Powder, Oregon, United States. The large site covers parts of Union and Baker counties, including parts of the Wallowa-Whitman National Forest.
Rock Point is an unincorporated community in Jackson County, Oregon, United States. Rock Point lies just north of an I-5 and Oregon Route 99 interchange along the Rogue River between the cities of Rogue River and Gold Hill.
Hat Rock State Park is a state park in the U.S. state of Oregon, administered by the Oregon Parks and Recreation Department. The park is located off the east side of U.S. Highway 730 in Hermiston, on the south shore of Lake Wallula behind McNary Dam on the Columbia River.
Wilmot Hyde Bradley was an American geologist who served as Chief Geologist of the U.S. Geological Survey from 1944 to 1959, and as President of the Geological Society of America in 1965. He was the tenth Chief Geologist, and his tenure was the longest of any Chief Geologist at the time.
Hyde Glacier is a short glacier flowing east through the Edson Hills to join Union Glacier, in the Heritage Range, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1961–66, and was named by the Advisory Committee on Antarctic Names for William H. Hyde, an ionospheric scientist at Little America V Station in 1958.
Paleontology in Oregon refers to paleontological research occurring within or conducted by people from the U.S. state of Oregon. Oregon's geologic record extends back approximately 400 million years ago to the Devonian period, before which time the state's landmass was likely submerged under water. Sediment records show that Oregon remained mostly submerged until the Paleocene period. The state's earliest fossil record includes plants, corals, and conodonts. Oregon was covered by seaways and volcanic islands during the Mesozoic era. Fossils from this period include marine plants, invertebrates, ichthyosaurs, pterosaurs, and traces such as invertebrate burrows. During the Cenozoic, Oregon's climate gradually cooled and eventually yielded the environments now found in the state. The era's fossils include marine and terrestrial plants, invertebrates, fish, amphibians, turtles, birds, mammals, and traces such as eggs and animal tracks.
The Astoria Formation is a geologic formation in Washington state & Oregon. It preserves fossils dating back to the early to middle Miocene.
The Snowshoe Formation is a geologic formation in Oregon. It preserves fossils dating back to the Toarcian to Bathonian stages of the Early to Middle Jurassic period.
The Weverton Formation is a quartzite geologic formation in Maryland, Virginia, West Virginia, and Pennsylvania. It is considered the basal member of the Chilhowee Group. The Weverton Formation dates back to the Cambrian period.
Medford Island is a small island in the San Joaquin River delta, in California. It is part of San Joaquin County, and managed by Reclamation District 2041. Its coordinates are 38.0371435°N 121.5113407°W.
