Leg 01 · The mountains
Out of the delta, over the divide
The run leaves sea level and spends its first day earning altitude — canyon grades, avalanche sheds, the continental divide at the Alberta line. Mountain weather is the one variable no plan controls: chain-up orders and pass closures can re-time a window with no notice. This is why the brief asks for your dates early and why the written plan must name how a weather hold would be communicated, not whether one is possible.
