Ernest Callaway Manning was British Columbia's Chief Forester from 1936 to 1941. He and Arthur Wellsley Gray, Minister of Lands (1933-1944), were instrumental in the creation of a number of provincial parks, including Tweedsmuir, Hamber, Wells Gray and Manning, which at one time encompassed Similkameen Falls -- until mine claims and private ownership caused the park's eastern boundary to be redrawn. Not sure if gender-specific outhouses were part of their vision, but Manning Park's gender boundaries should be redrawn as well.
