Linked terrain

A single five-minute cable car, the Urdenbahn, joins the two valleys, and crossing over and back in a day is routine. It is the only ski link — if it shuts, the way home runs by road via Chur.

Calibrated reanalysis, 1950–2025. Bars are each winter's mean base, rules each decade's mean. 2020–2025 holds 6 winters, not ten. Every figure here averages a full season, so none of them will match the readings for your chosen weeks above.
