20-21

From obs [2/20/21]: "We observed a large natural slide on Flanders Mountain that likely occurred on Thursday (2/18/21). The crown ranged from 2-5’, but it’s hard to gauge how wide it was, because it covered a lot of elevations. I think there is considerable overlap with the large slide that ran there earlier this season. We did not observe any other slides, collapsing, or cracking, but the wind did pick up in the early afternoon." Photo: S. Reinsel

Seen after getting back to our sleds after ski touring.

From obs: “Triggered a large slide with a snowmobile. Went all the way to the ground. Crown seemed to range anywhere from maybe 3 ft to 10 ft. Large slabs of snow broke free and slid for about 100 yards.”

While teaching class at history rock today I got an ECTP 30 in the basal facets. Structure was poor, 70cm settled storm snow on top of 45 cans of FCs and DH. Low elevation slopes now have a pretty solid slab on them it seems...

Here’s one more photo of some of the lower crown of that slide up Flanders. It was deep down lower!

We observed a large natural slide on Flanders Mountain that likely occurred on Thursday. The crown ranged from 2-5’, but it’s hard to gauge how wide it was, because it covered a lot of elevations. I’m including a photo with a rough approximation of where it broke—I think there is considerable overlap with the large slide that ran there earlier this season. We did not observe any other slides, collapsing, or cracking, but the wind did pick up in the early afternoon.

Saw evidence of a natural avalanche on an east aspect in the Flanders drainage today. Avalanche appeared to have happened in the last day or two and appeared to have slid at the ground. Visibility made it difficult to determine the extent of the slide.
