About Weir — Notre-Dame-de-la-Merci

Steep Laurentian gneiss cliff — 90-100m of vertical to overhanging sport and trad, surrounded by dense boreal forest. Steep sport lines shed rain fast, but base seepage and high canopy humidity delay lower-section drying.

Region: Weir
Rock type: Gneiss
Aspect: south-facing
Altitude: 280m
Exposure: low
Seepage: medium
