Ferry boats are as much a part Washington’s Puget Sound region as rain, salmon and the Seahawks. In fact, Washington State Ferries operates the largest ferry system in the U.S., carrying more than 22 million passengers to 20 different terminals.

The State Archives has a collection of State Ferries schedule pamphlets going back decades. This collection is the first Archives Treasure for June. The schedule featured below is from 1956.
