This image shows a train headed by a steam locomotive of the era as it waits at the Hanging Bridge, where it was common to stop for several minutes to allow passengers to view the canyon.
The description states:
HANGING BRIDGE IN THE ROYAL GORGE
The Grand Canyon of the Arkansas is nearly ten miles in length, extending from near Canyon City to Parkdale. About midway is the Royal Gorge, the deepest and narrowest part of the Canyon, where the walls rise to a height of 2,500 feet and the river channel is so restricted that the railroad is carried over the stream by a bridge suspended from the rocks above.
–Again here, the fanciful colors of the rocks and foliage are the result of manual colorization of the original black and white photograph. This image likely dates from the 1930s.
