Photograph of Mount Lowe Railway circular bridge and track, California, [s.d.]. In the background at center, a small circular section of track can be seen curving along a mountain wall. Poles connected by wires run adjacent to the track. The remainder of the track can be seen along the mountain in the background at left. Below the track, a steep incline overgrown with vegetation is visible. Another track is also visible near the top of the mountain. The track along the top of the mountain curves greatly along the mountain wall. Poles are also visible along the track. Between the two tracks, a large flagpole and flag can be seen on the mountain.
