Seward Peninsula

This land bridge aided in the migration of humans, as well as plant and animal species, from Asia to North America.

The U.S. Air Force operates a radar station at the "Tin City" site, 7 mi (11 km) southeast of Wales.

The largest include the Koyuk, Kuzitrin, Niukluk, Fish, Tubuktilik, Kiwalik, Buckland and Agiupuk rivers.

These play a vital role in the subsistence lifestyles of many peninsula residents and ease travel, hunting, and fishing.

Most peninsula rivers have at least a small yearly run of several varieties of salmon, as well as Dolly Varden trout, Arctic grayling, whitefish of various species, northern pike, and burbot.

The Seward Peninsula is the westernmost limit of distribution for the black spruce, Picea mariana, a dominant overstory species of the region.

If completed, the project would cost an estimated US$65 billion and would be the world's longest tunnel at 64 mi (103 km) long.
