Captioned 'Mighty "T" in Lock, 1938,' this album page records the light cruiser USS Trenton's transit of the Panama Canal locks, a key strategic route linking the Atlantic and Pacific fleets throughout the interwar period. Alongside a view of a merchant vessel navigating the open canal channel and a photograph of a jungle waterfall along its banks, the page reflects the fascination American sailors held for the canal's engineering marvel and the surrounding tropical landscape during a routine but memorable fleet passage.
