There is a lot to see in this photo.  At the top right is the mine spur, featuring a handcar mine train.  In the middle is the four section trestle bridge, which replaced the operating Erector drawbridge that had been in this spot until the 1953 revisions.  Finally, you can see where the elevated lake area loop ducks under the first section of the trestle bridge to cross the lake at water level and run under the waterfall.
