With hopes of finding an inversion, we planned to sled up toward Summit Glacier for some alpine turns. Although an inversion was present, it extended higher than expected, making route-finding in the lower alpine and upper treeline nearly impossible. We pivoted to the trees below Summit to investigate the January 26 SH/MFcr layer, which has been lingering 50–100 cm below the surface. In a wind-loaded convexity with over 4.5 m of total snow, we found this layer buried 85 cm down. An Extended Column Test produced a hard result that propagated across the column (ECTP 28), confirming the layer remains capable of propagation in specific terrain features. While heading up toward Bryant Lake, we observed a size 1.5 avalanche with sled tracks over the crown, suggesting it was likely triggered by a rider approximately 48 hours prior. This observation increases our confidence that wind slabs are present in specific areas of the upper treelined and alpine.
