Jim Creek Naval Radio Station

[1] The 5,000-acre (2,000 ha) site is largely forested in the foothills of the Cascades north of Seattle; the nearest city is Arlington, Washington.

The floor of the valley under the antenna is covered with an elaborate network of buried cables that serve as the ground system for the transmitter.

This station is part of the command system which, in the event of a nuclear war, would transmit launch orders to US ballistic missile submarines in the Pacific fleet.

[2] Jim Creek includes a regional outdoor recreation area for active duty personnel, reservists, retirees, DoD civilians, and sponsored guests.

Natural mountain lakes provide a habitat for wildlife including beavers, river otters, waterfowl, and bald eagles.
