the Arctic 1862: Gold Rushes in the Pacific Northwest
For some time after the Oregon Treaty, Britain's naval base on Vancouver Island was its only major presence in the Pacific Northwest. However in the late 1850s multiple gold strikes began drawing large numbers of prospectors from the United States to the region. In an attempt to maintain control of this influx and preempt any secessionist movements, the British announced the new colonies of the Queen Charlotte Islands, British Columbia, and the Stickeen Territories. Of the three, only British Columbia was really viable and soon absorbed both the other two and Vancouver Island.

1861–1867 Cariboo Gold Rush▲
Gold was discovered in the Colony of British Columbia at Hills Bar in 1858, on the Horsefly River in 1859, followed by more on Keithley Creek and Antler Creek in 1860. When these discoveries were widely publicized in 1861, a gold rush was triggered, with a massive influx of people into British Columbia, leading to the founding of several towns, such as Barkerville.
1861–1863 Stikine Gold Rush▲
Alexander "Buck" Choquette discovered gold on the Stikine River, in what was then part of North-Western Territory (but now part of British Columbia, Canada), leading to the short-lived Stikine Gold Rush.
