The answer

Victoria Falls Bridge, Zambia/Zimbabwe border · ZM · Photographed 1905

How the AI detective did

The AI placed its guess 31 km from the real location (it guessed Batoka Gorge, below the falls).

This is the great falls crossing itself — but I slide my pin down the zigzag gorges below the falls and date the steelwork a decade after the golden rivet.

The evidence the AI read

• architecture: Two riveted steel cantilever arms reach toward each other high above a gorge, with staging on each bank and the gap not yet closed. — A great steel arch caught mid-construction — a railway crossing being thrown over a chasm in a single bold span.
• terrain: The river below runs boiling white through a narrow sheer-sided rock slot, bending directly beneath the unfinished span. — A young, violently cut gorge — the kind of chasm found immediately downstream of an immense waterfall.
• vegetation: Dense evergreen bush clings to every crack and ledge of the gorge walls, from rim to waterline. — Spray-fed rainforest in otherwise dry savanna latitudes — a microclimate created by the falls themselves.
• era_marker: The image is a coarse halftone from a printed page, its dot screen plainly visible; the engineering is riveted lattice steel. — A press photograph from the imperial railway age — the 1900s, when such spans made world news.
