How the crowd plays it
"Perito Moreno Glacier" is what this prompt harvests from almost everyone — that reliability is what makes rarity measurable. Even "Mendenhall Glacier", the connoisseur's decoy, is banked at just 15 points: the mirror has seen it a thousand times.
The deep water of this prompt belongs to answers like "Hubbard Glacier" (85). Rarer still is "Jostedalsbreen", the One in a Noillirk gem: find it under a 25-second clock and a single prompt has carried you a full kilometre down.
Playing this prompt backwards
When this question surfaces in a dive, your 25 seconds are best spent in reverse: first, name the Plankton answer silently and let it go; second, refuse the Too Clever answer unless the clock is dying; third, search your second page — the runner-up, the older one, the one from the smaller place. In geography, that means remembering that think of the atlas backwards: instead of asking 'what do I know?', ask 'what does everyone else know?' — then sail past it. The first three countries anyone names are Plankton. The ones you have to picture on a map before you can spell them are where the depth is.
