Territoire du Nord-Ouest
In 1862 during the Stikine Gold Rush, part of the North-Western Territory became the Stickeen (Stikine) Territory when the Stikine became inundated by American miners and, to prevent any resulting American claims to or agitation for the region, Governor James Douglas of the Vancouver Island and British Columbia colonies declared the area a British territory. The coastal area at the mouth of the Stikine was part of Russian America at the time, but the British had rights of free navigation to the Stikine by treaties in 1825 and 1839 as well as a lease of coastal lands to the south of it. The boundary of the North-Western Territory in this region, and likewise the Stickeen Territories created from it, south of and northwards from the Stikine, had been set as "ten marine leagues" from the sea, but this remained undefined until the Alaska Boundary Settlement of 1903. The North-Western Territory's boundary with Russian America north of the 60th Parallel had been set at the 141st line of longitude by the Treaty of St. Petersburg in 1825.
