David Flanigan wanted the better building timber growing on the mesa: pine, spruce and fir. Cottonwood and ash in the canyon were poor substitutes, and hauling lumber by wagon could take a week or more. The gravity tram began moving lumber in 1901, using about 50,000 feet of baling wire between two timber structures 3,300 feet apart and more than 2,000 feet vertically. It carried hundreds of thousands of board feet for canyon buildings and nearby settlements, including the original Zion Lodge. The operation ended in the mid-1920s.
