Fun facts

A surveyor employed by the US government reportedly named McMicken Island after himself. The State of Washington purchased McMicken Island in 1974 for $133,000. Harstine Island - often spelled Hartstene, Harstene, and Hartstine - was named for Lieutenant Henry J. Hartstein, a member of the Wilkes Expedition. Later in life, Hartstein and his wife changed their surname to "Hartstene" to avoid people mispronouncing it, and mapmakers followed suit. The current spelling of "Harstine" was made up by island residents and mapmakers in the early 1900s, and the Washington Legislature made that spelling official in 1997. Other islands in southern Puget Sound named for members of the Wilkes Expedition include Maury Island and Stretch Island (after the gunners mate Samuel Stretch).
