Notes

From obs: "Skied the whitebark glade on Flanders and got several whumpfs at the mid and upper elevations. Light overnight and continued wind loading. There was a recent avalanche that appeared to be a wind slab with decent propogation on a north facing rocky slope. Visibility was too poor to get a good look or photo. "
