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 the government of the U.S. state of Oregon, is first in the line of succession to the governor. The duties of the office are auditor of public accounts, chief elections officer, and administrator of public records. Additionally, the secretary of state serves on the Oregon State Land Board and chairs the Oregon Sustainability Board. Following every United States Census, if the Oregon Legislative Assembly cannot come to an agreement over changes to legislative redistricting, the duty falls to the secretary of state.

Stylemys is the first fossil genus of dry land tortoise belonging to the order Testudines discovered in the United States. The genus lived in temperate to subtropical areas of North America, Europe, and Asia, based on fossil distribution. The genus was first described in 1851 by Joseph Leidy. The tortoise was common in the prehistoric Badlands, especially Nebraska and South Dakota. The species has also been found in the formations in and around Badlands National Park. Fossil fragments have also been found in the Palm Park Formation of New Mexico.

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.
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.
