The original Cariboo Gold Rush was a period of feverish migration of workers into the Horsefly Creek area in British Columbia in 1859 following the first gold discovery by Peter Curran Dunlevey.  This was closely connected by subsequent strikes at Keithley Creek and Antler Horns Lake in 1860; and by 1862, widely publicized stories surrounding prosperous finds throughout the Williams Creek district resulted in a full swing gold rush.
