Map of the United States

Exhibiting the various Trading Depots or Forts occupied by the British Hudson Bay Company connected with the Western and northwestern Fur Trade.

Compiled in the Bureau of Topographical Engineers from the latest authorities, under the direction of Col. J. J. Abert, by Wash: Hood.

1838

Showing Oregon Territory used during Congressional Debates about the Status of Oregon Country. The Hood map follows Aaron Arrowsmith’s map of 1834.

Hood’s landmark map of the Oregon Country was integral to political debates about the area, its place in the growing United States, and its boundary with Britain. It was made by Washington Hood, a Captain in the US Army and one of the first members of the fledgling Corps of Topographical Engineers, in 1838.

The map depicts North America west of the Mississippi River, which is not shown. In geography, the map closely follows Aaron Arrowsmith’s 1834 map of North America and adopts a similar, clean style. In the “Territory of Oregon,” a designation the area did not yet officially have, the Columbia River is the dominating feature, with forts and outposts of the Hudson’s Bay Company (HBC) marked. To the north, the “British Territory” is demarcated by a dotted and dashed line at the 49th parallel. The choice of this boundary was not clear cut and reveals the intense debates that occurred around the time this map was made regarding Oregon’s status within the United States.

Ernest Voorhis [1859–1933] in Historic Forts and Trading Posts mistakenly says this map shows Jasper House, “built in 1799 at outlet of Brûlé Lake and called Rocky Mountain House” [1].
