The answer

Champagne Pool, Wai-O-Tapu, Rotorua, New Zealand · NZ

How the AI detective did

The AI placed its guess 139 km from the real location (it guessed Kawhia coast, Waikato, New Zealand).

An orange-rimmed cauldron on the central volcanic plateau — but I pin the hot-water sands at Kawhia on the west coast, one range too far west of the geothermal valley.

The evidence the AI read

• terrain: A broad, steaming hot pool sits in a pale sinter basin, its shoreline traced by a vivid orange shelf that follows every bay and headland of the rim. — The orange collar is mineral precipitate forming at a stable hot-spring edge — a large geothermal cauldron rather than a volcanic crater lake.
• climate: Thick steam rolls low across the water and drifts inland under a cool, partly cloudy sky. — Steam condensing this heavily means crisp temperate air over near-boiling water — a mid-latitude geothermal field, not a tropical spring.
• vegetation: Dark plantation-style conifers stand in even ranks on the hills behind, beside slopes of low green scrub. — Exotic pine plantations alongside native scrub are the signature of a southern-hemisphere forestry country.
• terrain: The pool's pale silica collar builds outward in smooth lobes over older, orange-stained terraces. — Long-lived silica deposition points to a mature geothermal system on a rifted volcanic plateau.
