stream in the western Yukon Territory, Canada, rising near Dawson and flowing 20 mi (32 km) northwest to the Klondike River. In it gold was found by George Washington Carmack on Aug. 17, 1896, setting off the gold rush of that year into the Klondike Valley. The creek, formerly called Rabbit Creek, was renamed Bonanza Creek to mark Carmack's strike. See also Klondike River.
