Lieutenant Owen Stanley of the British Royal Navy kept a journal
detailing his personal experiences on HMS Terror. The journal has been
housed at the University of Toronto’s Thomas Fisher Rare Book Library
since 1971.

Stanley was the surveyor on the HMS Terror on an 1836
expedition, nine years before the Northwest passage expedition. A book
of his watercolours from the voyage is also kept at the Rare Book
Library. These Sketch shows the HMS Terror in the Ice of the Northwest Passage
