Bluefish Caves

Bluefish Caves is an archaeological site in Yukon, Canada, located 54 km (34 mi) southwest of the Vuntut Gwichin community of Old Crow, from which a specimen of allegedly human-worked mammoth bone has been radiocarbon dated to 24,000 years before present (BP), earlier than the generally accepted age for habitation of the New World.[1]

There are 3 small caves in the area.[2]


Bluefish Cave was initially known to the local First Nations, but was popularized by a fishing expedition in 1976, and later by researchers. This site is made up of three small caves, ranging from 10 to 30 m3 (350 to 1,060 cu ft).[3] The first cave contains various animal bones that appeared to have been dragged there by predators, but findings of tool marks and some tools themselves point to a human presence.[4]

The Old Crow Flats, another important area with early human presence, are located about 75 km northeast of the Bluefish Caves.[5]


The site was excavated by archaeologist Jacques Cinq-Mars between 1977–87, and the initial radiocarbon dating suggested an age of 25,000 before present (BP).[6] This was considered controversial as it was in contrast to the Clovis-First theory, widely accepted by academics at the time, which considered the earliest settlement date of North America to be around 13,000 BP.[7] A review of the site in 2017 found it to be 24,000 years old,[8] lending support to the "Beringian standstill" hypothesis - that the ancestors of Native Americans spent considerable time isolated in a Beringian refuge during the Last Glacial Maximum before populating the Americas.[9]
