Photograph depicts Mr. Crysdale sitting on a velocipede on the Sallus Creek ("14 Mile") Pacific Great Eastern Railway trestle with an estimated date of very late July 1915 or later. "Canadian Railway and Marine World" reported that track had been laid to 14 miles North of Lillooet by July 30, 1915 (CR&MW , Sept 1915, p341, c2). 14 miles North of Lillooet is approximately 20 rail lengths beyond the North end of this trestle, leading to a "best estimate" of very late July 1915 as the earliest date for this photograph. The velocipede depicted is a 3-wheel, manually propelled vehicle operated by a push-pull (back & forth) action on the actuating handle.
The ca. 1921-1927 “PGE Bridge List” from the notebook of William H. Hewlett (1914-1968) references a Mile 13.7, 14 Mile Creek, frame trestle, 905 ft. long, 182 ft. high, 61 spans of 14.8 feet in the Lillooet Subdivision. A “PGE Track Profile” drawing shows this trestle was on a 1.55% grade and a 12 degree left hand curve. While the drawing had been revised at least twice (with an unknown date for the most recent revision), the pre-“Lillooet Diversion of 1931" mileage figures confirm that the 1915 “Mile 13.7" was in agreement with a more recent hand written note “Sallus Creek”. The trestle appears to have gone by the names "14 Mile" trestle, "13.7 Mile Trestle", and "Sallus Creek" trestle.
