River flowing through a rocky canyon in the Imperial Valley, [s.d.]

Photograph of a river flowing through a rocky canyon in the Imperial Valley, [s.d.]. The river flows across the image from left to right. Steep rocky cliffs can be seen on both sides of the river. In the foreground at right, a wooden bridge crosses the river, and small horse-drawn vehicle can be seen crossing the bridge, headed away from the viewer.

该照片为帝国谷（Imperial Valley）内河流穿岩石峡谷的景观留影，无确切拍摄日期。河流自画面左侧向右侧流淌，两岸均可见陡峭的岩石崖壁。画面右侧前景处，一座木质桥梁横跨河面，一辆小型马拉车辆正行经该桥，朝着远离观察者的方向行进。
