About Porcupine

The Porcupine River (Ch’ôonjik in Gwich’in) is a 916 km (569 mi) tributary of the Yukon River in Canada and the United States. It rises in the Ogilvie Mountains north of Dawson City, Yukon, Canada. From there it flows north through the community of Old Crow, veers southwest into the U.S. state of Alaska, and enters the larger river at Fort Yukon, Alaska. It derives its name from the Gwich'in word for the river, Ch'oonjik, or "Porcupine Quill River".

The Porcupine caribou herd, whose range includes the Arctic National Wildlife Refuge (ANWR) in Alaska, gets its name from its calving grounds around the Porcupine River.

Possible (but disputed) evidence of the oldest known human habitation in North America comes from a cave on one of the Porcupine's tributaries, the Bluefish River. Many apparently human-modified animal bones have been discovered in the Bluefish Caves. Radiocarbon dating has assessed them as 25,000 to 40,000 years old—several thousand years earlier than the generally accepted date for human habitation of North America.
