In 1805 the Lewis and Clark expedition explored the area. John Jacob Astor's fur depot, Astoria, was founded in 1811. Disputes for control of Oregon between American settlers and the Hudson Bay Company were finally resolved in the 1846 Oregon Treaty, in which Great Britain gave up claims to the region.
The state varies from rain forest in the Columbia Gorge to barren desert in the southeast, which still meets the technical definition of a frontier.
Oregon had one of the largest salmon-fishing industries in the world, although ocean fisheries have reduced the river fisheries in recent years. Tourism is also strong in the state; Oregon's evergreen mountain forests, waterfalls, pristine lakes (including Crater Lake National Park), and scenic beaches draw visitors year round. The Oregon Shakespeare Festival is a tourist draw near its Californian border which complements the area's scenic beauty and opportunity for outdoor activities.
Crater Lake National Park, Mount Hood, and Bonneville Dam on the Columbia are major tourist attractions. Other points of interest include the Oregon Dunes National Recreation Area, Oregon Caves National Monument, Cape Perpetua in Siuslaw National Forest, Columbia River Gorge between The Dalles and Troutdale, Hells Canyon, Newberry Volcanic National Monument, and John Day Fossil Beds National Monument.
