The formation was originally named by Raymond Thorsteinsson for a sequence of calcareous, graptolitic mudrocks on northern Devon Island situated between the Douro Formation below and the Sutherland River Formation above.<ref name="Thorsteinsson1963" /> The latter formation is now considered synonymous with the Goose Fiord Formation.<ref name="MayrPackard1994" /> The Devon Island Formation extends from the west coast of Devon Island through the Grinnell Peninsula, and well across the southern part of Ellesmere Island.<ref name="MayrPackard1994" />
