The Oregon Trail, the Santa Fé Trail, the Spanish Trail and the Gila Route, had become quite well known by the early ’thirties and after the discovery of gold in California in ’forty-nine carried many people and much traffic across the continent. =Origin of the Oregon Trail.=--At Bellevue the Nebraska State Historical Society erected, June 23, 1910, a monument a part of the inscription on which reads: Commemorative of the Astorian Expedition organized June 23, 1810, by John Jacob Astor’s American Fur Company. This Expedition discovered the Oregon Trail which spread knowledge of the Nebraska country leading to its occupancy by white people. John Jacob Astor’s purpose in organizing the Pacific Fur Company, a subsidiary of the American Fur Company, was to establish himself and American control in the already disputed Oregon country.[34] As a result two expeditions were fitted out to go to and establish trading posts in Oregon with a central control or main post at Astoria. One of these expeditions went by water around Cape Horn to “carry out the people, stores, ammunition and merchandise, requisite for establishing a fortified trading post at the mouth of the Columbia River.” The other “conducted by Mr. Hunt, was to proceed up the Missouri, and across the Rocky Mountains, to the same point: exploring a line of communication across the continent, and noting the place where interior trading posts might be established.”[35] The overland expedition, consisting of about sixty men with four boats left their winter quarters in Missouri and proceeded up the river in the spring of 1811. They deviated somewhat from Lewis and Clark’s route by leaving the Missouri River at the mouth of the Grand River, near where the Pacific extension of the Chicago, Milwaukee, and St. Paul railroad crosses. They seem to have gone across the country north of the Black Hills into Wyoming to the Wind River and Wind Mountains south of the Yellowstone Park, using present-day terms for locations; thence a short distance to the head waters of the Snake River, a part of the Lewis and Clark route, which with some deviations they followed to the Columbia. At the mouth of the Columbia they met the sea party, and on July 28, 1812, a party of six men started back with dispatches. They wintered near Scott’s Bluff, Nebraska, having crossed the mountains substantially along the line afterwards known as the Oregon Trail. In the spring of 1813 they continued down the Platte to the Missouri. This trip proved the possibility of a direct route avoiding the long roundabout journey by way of the headwaters of the Missouri River. The evolution of the Oregon Trail has been summarized by Albert Watkins, Historian of the Nebraska State Historical Society, in Collections, Vol. XVI, p. 26, as follows:[36]
