Entire Northerly aspect of Rochester Ridge from Christmas Tree down to the Other Runs had multiple unconnected Storm Slabs that occurred during the High PI and Winds on 20250401. Photos 3 and 4 show Christmas Tree and next Chute Down that were at least 300 feet Wide and connected.
Slope Cut today (20250402) easily triggered Touchy Storm Slab, Max Depth: 30cm/Left Flank, Min Depth: 15cm/Right Flank, Storm Slab had a contributing factor of Wind Loading due to cross loading from the WNW Winds, Average Depth: 20cm; Weak Layer Light density snow (Fist) that fell after the first 5cm had fallen during the storm (Observation of Weak Layer indicated PP/Broken Stellar Arms); Bed Surface: On top of this 5cm layer, Pencil minus, Dense/Heavy snow that fell initially when the storm began with warm temperatures, plus this firmness was aided in hardness by the venting warm snowpack; Bonding good to the pre-storm new snow/old snow surface; Slab Hardness 4 finger minus; Slab moisture: Dry; Of Note: Primary Observation directly after event, and Second Observation 45 minutes later after Snow Surface and Slab had taken on minimal heat and was then beginning to get Damp, and Slab was even more Reactive.
