Noticed a natural avalanche in Room of Doom this morning while skinning up lower Mineral fk. Didn't see this one reported yesterday so assuming it occurred overnight. Difficult to tell how large this was but appeared to be similar in size (possibly larger) than the avalanche reported near Mongo No on 3/28. This avalanche appeared to break just below the steep rocky terrain on skiers left side of the bowl. No pictures due to early morning and flat light.
