2nd remotely triggered slide while continuing up toward the Mill Creek/Parley's ridgeline. This slide sympathetic'd out another, smaller adjacent 'slope' 30' wide and 18" deep on the west side of the ridgeline. Collapsing and shooting cracks noted much of the way.

Photo of rocky terrain is the sympathetic. All running on the weak faceted snow formed during the 1st week of January period of high pressure. No rime crust noted above the facets.

Last photo shows the tensile cracks within the snow just off the Parley's/Mill Creek ridgeline on north facing terrain. Not steep enough for this avalanche to slide...but commonplace where wind loading from Wed/Thurs occurred...with the Thurs/Fri storm snow above.
