The first Native Americans arrive in the Pacific Northwest by way of Siberia and Alaska. The earliest groups survive by fishing and hunting large game. Around 8000 BCE Native American settlements are found across the geographical region now known as Oregon, with a majority concentrated along the lower Columbia River, in the western valleys, and around coastal estuaries. Many Oregon names are derived from these Native American tribal names, including Multnomah, Willamette, and Clackamas.
Following exploration by the Spanish and French, in the 17th and 18th centuries, Oregon was mapped by the Lewis and Clark expedition in their search for the Northwest Passage. In 1846, the border between U.S. and British territory was formally established at the 49th parallel - the part of the territory that was given to Britain would ultimately become part of Canada. Oregon was officially admitted to the union as a state on February 14th, 1859.
