Date of Observation: April 11, 2019 12:40 PM
Location of Observation: Oakes Gulf
While the east side of Mt. Washington remained clear and calm throughout the day, consistent southeast winds made for steady wind-loading on isolated terrain features in the eastern half of the ravine and on the entire slope in the western half. The first slide (first additional photo) was triggered underneath the rock buttress near the base of Halfpipe Gully: SS-AS-R2-D1.5. Skier was not caught or carried, uninjured. The second avalanche (main photo) occurred on the slope skier’s-left of Double Barrel: SS-ASr-R3-D2. Appears to have been remotely triggered by a party of three, one of the party members may have been caught (was really hard to see exactly what was happening from across the ravine.) Third slide (no photo) was triggered underneath a rock buttress on the skier’s-right side of Airplane Bowl: SS-AR-R1-D1. Snowboarder was not carried or caught, uninjured. In addition to these human-triggered slides, there were lots of recent crown lines in the buttress area of Oakes, most notably underneath the cornice at the start of Halfpipe Gully (second additional photo). All slides occurred within 10 minutes of each other. Another reminder that it’s not quite spring up high yet.
