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 Secretary of State of Oregon, an elected constitutional officer within the executive branch of government of the U.S. state of Oregon, is first in line of succession to the Governor.

The Provisional Government of Oregon was a popularly elected settler government created in the Oregon Country, in the Pacific Northwest region of North America. Its formation had been advanced at the Champoeg Meetings since February 17, 1841, and it existed from May 2, 1843 until March 3, 1849, and provided a legal system and a common defense amongst the mostly American pioneers settling an area then inhabited by the many Indigenous Nations. Much of the region's geography and many of the Natives were not known by people of European descent until several exploratory tours were authorized at the turn of the 18th and 19th centuries. The Organic Laws of Oregon were adopted in 1843 with its preamble stating that settlers only agreed to the laws "until such time as the United States of America extend their jurisdiction over us". According to a message from the government in 1844, the rising settler population was beginning to flourish among the "savages", who were "the chief obstruction to the entrance of civilization" in a land of "ignorance and idolatry".
The Oregon Coast Range, often called simply the Coast Range and sometimes the Pacific Coast Range, is a mountain range, in the Pacific Coast Ranges physiographic region, in the U.S. state of Oregon along the Pacific Ocean. This north-south running range extends over 200 miles (320 km) from the Columbia River in the north on the border of Oregon and Washington, south to the middle fork of the Coquille River. It is 30 to 60 miles wide and averages around 1,500 feet (460 m) in elevation above sea level. The coast range has three main sections, a Northern, Central, and Southern.

Feminist Formations is a peer-reviewed academic journal established in 1988 as the NWSA Journal ; the name was changed beginning with the Spring 2010 issue. It publishes interdisciplinary and multicultural feminist scholarship in women's, gender, and sexuality studies linking feminist theory with teaching and activism. In addition to its essays focusing on feminist scholarship and its reviews of books, the journal regularly publishes special issues focused on topics especially important in the field of women’s, gender, and sexuality studies and also features vibrant cover art and poetry and cutting-edge feminist artists and poets. The journal is edited by Patti Duncan, a professor of Women, Gender, and Sexuality Studies at Oregon State University, and is published three times per year by the Johns Hopkins University Press.

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.
Siletzia is a massive formation of early to middle Eocene epoch marine basalts and interbedded sediments in the forearc of the Cascadia subduction zone, on the west coast of North America. It forms the basement rock under western Oregon and Washington and the southern tip of Vancouver Island. It is now fragmented into the Siletz and Crescent terranes.
Spathorhynchus is an extinct genus of amphisbaenians or worm lizards that existed from the Middle Eocene to the Early Oligocene in what is now Wyoming. It includes two species, the type species S. fossorium, named in 1973 from the Middle Eocene Bridger and Wind River Formations, and the species S. natronicus, named in 1977 from the Lower Oligocene White River Formation. Spathorhynchus belongs to the family Rhineuridae, which includes many other extinct species that ranged across North America at various times in the Cenozoic but only has one surviving member, Rhineura floridana, from Florida. Spathorhynchus differs from all other rhineurids except Dyticonastis from the Late Oligocene-Early Miocene of Oregon in having a slightly widened, spatula-shaped snout tip with a low angle of about 30 degrees. The two taxa may be closely related, having evolved in isolation in western North America after the formation of the Rocky Mountains separated them from rhineurids further east.
