Over the Mountain

By the sixth day Mount Moon stops being scenery and becomes terrain, the ground tilting underfoot until Red regrets choosing the long way over the mountain rather than the zubat-infested route through it. Dania and Naoko peel off at a Pokemon Center, numbers dutifully exchanged — the interregional habit of trading contacts with anyone you've battled, on the faith that journeys loop old acquaintances back together. That prompts a conversation about image. Blue, eyeing his seventy-odd followers, insists that great feats aren't enough: influence goes to those who make themselves matter, the way Professor Oak and Giovanni do. His example against is Bill Sonezaki — stupid-smart, camera-shy, rich enough to buy a city, and so politically invisible that when he champions a real problem like the broken human-storage system, almost no one signs on. Leaf, who wants to be judged on what she does, isn't sure how to build a public face without accomplishments behind it; Red lands between them, and notices Leaf reaching for her phone more often as the talk sinks in.

The excavation site sprawls below them like a scar — seven digs, thirty workers, ACE trainers facing outward on the perimeter. Jon Ryback gives the tour: the fossils belong to a tangle of competing backers (the museum wants whole specimens, Cinnabar Labs grinds them up trying to revive them, private collectors hoard), and the mountain chain itself is split between Pewter, Cerulean, and Viridian, held together for now only by third-party security and uneasy collaboration. He walks them through deep time — distance across the foothills standing in for hundreds of millions of years — and fields Leaf's journalistic ambush on radiometric dating: carbon dating's sixty-thousand-year ceiling, the problem of unknown initial quantities, the embarrassing young dates that surface now and then. He answers each cleanly: other isotopes reach far deeper; you cross-check two uranium-lead decay systems on a Concordia diagram so you never need the starting amount; and anomalous dates come from known edge cases like fresh volcanic rock — like using a thermometer to check for fever while standing in a cold shower.

Beneath the science, friction: a glowering geologist, and a string of small tremors no one can quite place. The visit ends with the ground heaving and a dust cloud rising over one of the digs — "Paul to all points, we have a Tier 1 on site!" — and Blue grinning that the day won't be boring after all.

Lesson — A method's domain of validity. Leaf's three objections to radiometric dating are the standard ones, and Ryback dismantles them not by insisting the tool is perfect but by mapping where it works and where it doesn't: cross-checking two decay chains removes the dependency on an unknown starting quantity, and a wildly wrong reading on fresh volcanic rock is the tool used outside its range, not proof it's broken — the thermometer in the cold shower. A criticism that a method can fail only bites if you ignore the conditions under which it fails.
