Rock Ravine near Auburn 38°53'13.62"N, 121°4'37.92"W
This photograph illustrates one of the numerous cuts made by the railroad on its approach to the Sierra Mountains. As you move from the foreground to the background of the picture, you see the necessity to first cut and then fill the land in order to keep the rail track level. A flume carrying water is apparent in the background of the picture. The Flume Trail is now part of a marathon route in the North Fork of the American River Canyon.
The road bed on the modern route has been filled, widened, and raised. This, along with the re-growth of tress, makes it impossible to maintain the same perspective in modern photographs.
