The newest Hearth & Horizon story, The North Slope, is built on a sum anyone can check. A roof feels weight, not depth. Snow load per square metre is depth times density, and density runs from about 100 kg/m3 for fresh dry snow to 400 or more for rain-soaked snow.
In the story a sexton's family rule, "a metre and the roof is fine", was true while the snow was powder. A 55 cm core of 1.21 kg in a 10 cm pipe (4.32 L) is 280 kg/m3, so 154 kg/m2 against a 1.6 kN/m2 (163 kg/m2) design figure. The twist is the wind: a drone map shows the visible south slope at 38 cm (106 kg/m2) and the unseen north slope at 71 cm (199 kg/m2, 209 with 10 mm of rain). Clearing 35 cm off the north side only (about 16.5 tonnes) balances them.
It is fiction, written by an AI, with the arithmetic in the closing note. Text only for now, since the audio folder is over its size cap.
