Monongahela, Mosholu and Tonawanda are not trolls living under the Aurora Bridge. They were the last tall barquentine ships to leave Lake Union before the final span of the bridge was put in place in 1932. Although the Aurora Bridge was built high to allow large vessels to pass through, it could not accommodate these relics of commercial sail - even with their topmasts lowered, they still were higher than the bridge.
A fleet of surplus and seized vessels was moored in the middle of Lake Union during the time of World War I. It was a right of passage for young boys to row out to the ships in the middle of the night, climb aboard, and bring back a souvenir, such as a lantern, dining ware, or other relics.
