Red Flags Comments
No need to discuss the continued poor structure. Moderate loading with mod winds between 12:00-13:00. Found some touchy wind slab both HS and SS along ridgeline, 1-2' deep. Cracking in new snow and one odd large collapse @ 8,800' on a SW slope ascending the S side heading to Powder Park 1. Expect the winds and additional precip to instigate a natural cycle this afternoon-tomorrow morning.
