Oregon (/ˈɒrɪɡən, -ɡɒn/ ORR-ih-ghən, -⁠gon) is a state in the Pacific Northwest region of the United States. Oregon is a part of the Western United States, with the Columbia River delineating much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42° north parallel delineates the southern boundary with California and Nevada. The western boundary is formed by the Pacific Ocean.

Oregon has been home to many 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 to mid-16th century. As early as 1564, the 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 the strait now bearing his name. The Lewis and Clark Expedition traversed Oregon in the early 1800s, and the first permanent European settlements in Oregon were established by fur trappers and traders. In 1843, an autonomous government was formed in the Oregon Country, and the Oregon Territory was created in 1848. Oregon became the 33rd state of the U.S. on February 14, 1859.

Today, with 4.2 million people over 98,000 square miles (250,000 km2), Oregon is the ninth largest and 27th most populous U.S. state. The capital, Salem, is the third-most populous city in Oregon, with 175,535 residents. Portland, with 652,503, ranks as the 26th among U.S. cities. The Portland metropolitan area, which includes neighboring counties in Washington, is the 25th largest metro area in the nation, with a population of 2,512,859. Oregon is also one of the most geographically diverse states in the U.S., marked by volcanoes, abundant bodies of water, dense evergreen and mixed forests, as well as high deserts and semi-arid shrublands. At 11,249 feet (3,429 m), Mount Hood is the state's highest point. Oregon's only national park, Crater Lake National Park, comprises the caldera surrounding Crater Lake, the deepest lake in the United States. The state is also home to the single largest organism in the world, Armillaria ostoyae, a fungus that runs beneath 2,200 acres (8.9 km2) of the Malheur National Forest. (Full article...)

A Camas pocket gopher
The Camas pocket gopher (Thomomys bulbivorus), also known as the Camas rat or Willamette Valley gopher, is a rodent in the genus Thomomys of the family Geomyidae. First collected in 1829, it is endemic to the Willamette Valley in the northwest part of Oregon in the northwestern United States. It is the largest member of the genus, commonly known as smooth-toothed or western pocket gophers. The herbivorous gopher forages for vegetable and plant matter collected in large, fur-lined, external cheek pouches. Surplus food is hoarded in an extensive system of underground tunnels. The dull brown to lead-gray coat, changes color and texture over the year. The mammal's characteristically large, protuberant incisors are well adapted for use in tunnel construction, particularly in the hard clay soils of the Willamette Valley. The young are born toothless, blind, and hairless. They grow rapidly and are weaned around six weeks of age. The females have four mammary glands. The gophers make chattering sounds with their teeth. Males and females make purring or crooning sounds when together, while the young may make twittering sounds. The Camas pocket gopher is fiercely defensive when cornered, yet may become tame in captivity. While population trends are generally stable, threats to the species' survival include urbanization, habitat conversion for agricultural uses, and active attempts at eradication through trapping and poisons. In addition, it may fall prey to raptors or carnivorous mammals, or become host to a number of parasitic arthropods and worms. Scientists believe that the evolutionary history of the animal was disrupted when the cataclysmic Bretz floods washed over the Willamette Valley at the end of the last ice age. The floods nearly entirely covered the gopher's geographic range, which may have caused a genetic bottleneck as survivors repopulated the region after the waters receded.

Linus Pauling at graduation from OSU
Linus Pauling (February 28, 1901 – August 19, 1994) was an American quantum chemist and biochemist. Pauling is regarded by many as the premier chemist of the twentieth century, especially for the versatility of his contributions. He pioneered the application of quantum mechanics to chemistry, and in 1954 was awarded the Nobel Prize in chemistry for his work describing the nature of chemical bonds. Pauling received the Nobel Peace Prize in 1962 for his campaign against above-ground nuclear testing. Later in life, he became an advocate for greatly increased consumption of vitamin C and other nutrients. Pauling was born in Oswego, Oregon. In the 1930s he began publishing papers on the nature of the chemical bond, leading to his famous textbook on the subject published in 1939. It is based primarily on his work in this area that he received the Nobel Prize in Chemistry in 1954. In 1958, Pauling and his wife presented the United Nations with a petition signed by more than 11,000 scientists calling for an end to nuclear-weapon testing. Public pressure subsequently led to a moratorium on above-ground nuclear weapons testing, followed by the Partial Test Ban Treaty, signed in 1963 by John F. Kennedy and Nikita Khrushchev. On the day that the treaty went into force, the Nobel Prize Committee awarded Pauling the Nobel Peace Prize.

The Portland Streetcar at the Portland State University stop. The Portland Streetcar is a streetcar system in Portland, Oregon, that serves areas surrounding downtown. When opened in 2001, it was one of the first new streetcar lines in the United States since World War II and the first to use modern vehicles.

This evening we had what I call an excellent supper it consisted of a marrowbone a piece and a brisket of boiled Elk that had the appearance of a little fat on it. this for Fort Clatsop is living in high stile.
