The Cariboo Gold Rush was a gold rush in the Colony of British Columbia, which later became the Canadian province of British Columbia. The first gold discovery was made at Hills Bar in 1858, followed by more strikes in 1859 on the Horsefly River, and on Keithley Creek and Antler Creek in 1860. The actual rush did not begin until 1861, when these discoveries were widely publicized. By 1865, following the strikes along Williams Creek, the rush was in full swing.
Towns grew up, the most famous of these being Barkerville, now preserved as a heritage site and tourist attraction. Other important towns of the Cariboo gold rush era were Keithley Creek, Quesnel Forks or simply "the Forks", Antler, Richfield, Quesnellemouthe (which would later be shortened to Quesnel), Horsefly and, around the site of the Hudson's Bay Company's fort of the same name, Alexandria.
