This is an important and scarce 1838 map of the Oregon Territory by Captain Washington Hood. Prepared to 'illustrate the report of Senator Linn on a Bill to authorize the President to occupy the Oregon Territory,' this map covers present day Oregon, Washington, Idaho, Montana, Wyoming, California, Utah, Nevada and British Columbia. Based on Arrowsmith's 1834 map, with relevant updates, it extends from the Dixon Entrance in Canada south to Monterey Bay eastward to the Rocky Mountains, and illustrates the complicated rivers systems in the region. It predates the official establishment of the Oregon Territory, and unlike Arrowsmith's map, sets the northern boundary along the 49th parallel as per the 1818 compromise, while the southern border reflects the boundary settled in Addams-Onis Treaty of 1819.
In 1818, United States and Britain agreed to joint occupancy of the Oregon County. Both the British, in the name of the Hudson Bay Company, and the Americans, championed by John Jacob Astor's Pacific Fur Company, were eager to claim monopolistic right over the region. Astor's establishment of Fort Astoria on the Columbia River, identified here, only served to further tensions with the Northwest Company - the Pacific subsidiary of the Hudson Bay Company. The dispute would escalate, giving rise to the Oregon Boundary Dispute and the American expansionist slogan 'Fifty-four Forty or Fight!.' The dispute was not resolved until the 1846 Oregon Treaty which, through concessions on both sides, formally set the boundary at the 49th parallel.
Cartographically, the map features several interesting elements. The Great Salt Lake or the Youta or Bonneville, is curiously oblong in shape. The Gourd River southwest of Salt Lake becomes the Buenaventura River, flowing into 'Swamp Lakes and Islands.' A second Buenaventura River runs north into Monterey Bay. The Buenaventura is the last incarnation of the apocryphal River of the West, a long sought after speculative alternative to the Northwest Passage. Various posts of the British Hudson's Bay Company as well as the American Fur Company are noted throughout. The map also shows Lewis and Clark's route from Missouri headwaters to 'Canoe Camp' near the Lewis (Snake) River.
This map was compiled in the Bureau of Topographical Engineers from the latest authorities under the direction of Col. J. J. Abert. Topographic map by W. I. Stone after M. H. Stansbury. According to Senator Linn, this map was 'believed to be the most correct, and furnishes the most recent and authentic information of any yet published.' The map accompanied the historically important Report of Mr. Linn, Senate Document No. 470, 25th Congress, 2nd Session, dated June 6, 1838, to Accompany Senate Bill No. 206, to authorize the President to occupy the Oregon Territory, and was later re-issued in other reports. A map of historic significance, making it one of the most desirable maps of the region.
Howard Stansbury (February 8, 1806 - April 13, 1863) was an important surveyor, cartographer, and explorer who did his most important work in Utah during the middle part of the 19th century. Born in New York City, Stansbury trained to be a Civil Engineer. Shorty after getting married to Helen Moody of Detroit in 1827, Stansbury took a position with the United States Topographical Bureau. Under that organization he surveyed the James River in 1836, and the Illinois and Kaskaskia Rivers in 1837. In 1838, he oversaw the construction of a road from Milwaukee to the Mississippi River. Later in 1838, when the U.S Corps of Topographical Engineers was created, he joined as a first Lieutenant. With the Topographical Engineers he surveyed the Great Lakes, the harbor of Portsmouth, New Hampshire, and constructed Florida's Carysfort Reef Lighthouse. During the Mexican-American War he constructed fortification in the Dry Tortugas at the westernmost point on the Florida Keys. Upon achieving the rank of Captain, Stansbury received a commissioned to head a survey of the Great Basin that would ultimately become the crowning achievement of his career. His assignment was to survey the emigrant trails to California, including the Oregon Trail, as well as the Great Salt Lake, and report on the status of the growing Mormon Community in Salt Lake City. Working with J. W. Gunnison and Alfred Carrington, a Mormon scout, Stansbury produced a masterful survey of the region that had a lasting effect not only on the development of the Great Basin, but on the development of the west in general. Upon completion of his survey, Stansbury set out on the road to Washington, completing another important survey in the process. On the way, he fell off his horse, taking an injury from which he never fully recovered. Following the presentation of his report to Congress, Stansbury was charged with additional survey work around the Great Lakes. Upon the outbreak of the American Civil War, he was assigned to recruitment duties in Ohio and later Wisconsin. Shortly after starting work at this post he suffered an abrupt heart attack and passed away. He is buried in St. Paul, Minnesota.
