Checking for development of faceted melt-freeze grains, a particularly problematic weak layer once buried. Found them well-developed everywhere, in the top portion of the melt-freeze and rime crust from the last warm weather. Profiled three sites, the first immediately adjacent to the site profiled three days ago, and two at lower elevation. Checked for consistency in between sites. Found thick rime layers up high, so focused on lower elevation changes. The snowpack is now well-frozen, and all the lower layers are quite strong. No block tests were done because none were necessary. There was some moderate localized scour and windloading, and the windloaded areas gave a good preview of what can be expected when there is more load on the weak layers that are now on the surface, or in areas where windloading may have produced larger areas of thicker windslabs. Sluffs still ran when slopes over 40° were ridden, but they were much smaller, slower, and harder to release than they were three days ago. |

| Mini-slab triggered by a turn in a windloaded area. Windloaded areas are very sensitive, but still small and discontinuous in this area. Larger, thicker windslabs or new snow are likely to produce an avalanche cycle. | |||||||||||
