KSKA reports the village is about 20 miles up the Kobuk River from the community of Kiana, which is about 500 miles northwest of Anchorage.
Arctic archaeologist Doug Anderson says he's never seen a site quite like the one uncovered where so many houses were connected by a web of tunnels. The tunnels were dug about 4 feet deep.
Anderson believes about 200 people lived in the village, which he believes was a regional capital. Researchers believe the community dates from the late 1700s to the early 1800s, just before initial contact with explorers.
Researchers found signs that villagers lived closely with dogs. Researchers also found two sets of human remains in one dwelling.
