    Columbia and Snake River Timelines – Selected events From Selected Events Compiled by John Harrison at the Northwest Power and Conservation Council 6 to 16 Million Years Before Present: Huge lava flows create the Columbia Plateau. 5 MYBP : “Modern-day” Salmon are believed to have evolved in the ancient Columbia River 12 to 15 thousand YBP: More than 40 “Missoula Floods” sweep across the Columbia Region 458 Five Chinese monks sail past Japan, Kamchatka, the Aleutians, Alaska and down the northwest coast 1648 Russian explorers begin the trade in animal furs in North America 1792 Captain Robert Gray “discovers” the Columbia River mouth 1805 Lewis and Clark cross the Continental Divide into the upper Lemhi River. Large tribal communities supported themselves with harvest of steelhead, the so-called “white Salmon.” 1811 Astor Party founds Astoria. 1813 Astoria sold to Northwest Fur Company, is claimed by the British and renamed Fort George. 1823 Private fur companies begin to also commercially harvest and pack salmon. 1825 Beaver trapping begins to falter from depressed demand and low supply. 1827 Hudson Bay Company begins logging in the Fort George region. 1838 A Methodist Mission at The Dalles becomes the first non-Indian settlement in the Columbia River Gorge. 1843 Oregon Trail begins to see pioneers passing into the region. 1855 Treaties are negotiated between several Native American Tribes and the US Government 1859 Oregon becomes a state and the first large-scale irrigation project is built on the Walla Walla River. 1861 Commercial salmon fishing grew for almost 30 years, with harvest peaking in 1889.
