- Wind Loading, Poor Snowpack Structure
- Red Flags Comment
- <p>Wind loading slowed down as the day started. Last night there was plenty of avilable snow for transoprt and enough speed to move it. Poor sturcture in many places. </p>
Test slopes showed the old/new snow interface and a density change within the storm snow on steeper slopes. Saw a few artillery controlled slides near the highway to heaven traverse off twin lakes pass. (Pic.1) Another few small pockets on the way up grizz. Bed surface was a thin crust with handfulls of weak snow falling out underneath. (Pic. 3) ECT results were showing broken fractures 30cm and 68 cm down without propagation. Like in Hardesty, Wilson, Torrey & Diegel 's observation tests did not correlate with avalanche conditions in a representative location. Depth hoar is on 3mm gird in picture 2.

- <p>Would make this the number one problem for tomorrow as well. Seams like bulls eye avalanche data is centered around N/NE above 9500. </p> <p>These should start to settle out in the next day or so but still worth mentioning. Possibility of them stepping down into a persistent slab problem. On a variety of aspects above 10k. </p>
Around 7cm of new snow within the last 24 hours. Density changes within storm snow. Height of snow up to 140cm on N/NW aspects in upper LCC.
