Oregon, the Beaver State, is bounded by California and Nevada on the south, Idaho on the east, and Washington state to the north across the Columbia River, on which Portland, its largest city, is situated. The Cascade Mountains are Oregon's most prominent feature, dividing the state between wet and woody western and dry eastern segments. Agriculture and forestry are prominent in the economy, as well as salmon fishing and tourism to scenic sites such as Crater Lake and Mount Hood. The final destination on the Oregon Trail, Oregon was admitted as the 33rd state in 1859 with its capital at Salem.
