Despite the caption "Loading Rock", this image is in fact a ground-level view up to the deck of the north bridge approach showing a dump truck loaded with two large boulders in the process of tipping the dump bed to deposit the rocks onto the rock pile below. This shows the beginning of the rock fill portion of the north approach where it connected with the wooden bridge portion.
