This photo is one of those you gotta see it to believe it things. The locomotive is probably Baker White Pine #3 pulling a SVRy passenger consist. The notation on the back of the photo say it was a picnic excursion to Curry. The photo is actually on Baker White Pine's logging mainline on the trestle at Little Dean Crk. The photo caption says about 1922 which seems reasonable as the Baker White Pine built this new mainline in 1922. Perhaps the opening of the new mainline was part of the reason for the event. More rampant speculation would be that the excursion began at Baker with an SVRy engine bringing the consist to Curry which was the junction of the new logging line to the SVRy about 20 miles out of Baker and about 3 miles below McEwen, and then the Baker White Pine Engine might have taken the consist on a tour up the new line. The "Curry Line" as it is usually called, was according to word of mouth as well as personal observation of the old grade built to a high standard. Some say better than portions of the SVRy main.
