"Bottomless Pit" and "Bridge of Sighs"

The verso of this stereocard reads: "Are on the main route to 'Echo River' and a mile and a half from the entrance. The pit is of an immense depth and over it is thrown a substantial wooden bridge, across which visitors pass in the long route and towards 'Pensacola Avenue.' The pit presents a sight of awful sublimity when its steep sides are lighted up by the guide."
