About Bow Valley — Yamnuska

The premier multi-pitch limestone wall in Alberta. South-facing aspect combined with heavy valley winds creates rapid drying within hours of rain. Sits at the very edge of the Rockies, so prairie thermals dry it weeks earlier in spring than inner-range crags. Chert pockets become slippery and brittle when damp — dry-time modelling matters even when the surface looks fine.
