Wet Loose Avalanches in GNP

Below freezing in AM along the GTSR w/ 2-4 cm MFc at 5-6000'. Evidence of widespread WL cycle, all D1-1.5. Noted storm slab (est. 1.5' x 200') below Garden Wall in Haystack (photo attached) that released after being triggered by WL from above. Additional smaller storm slab was released in Haystack with same circumstance.  CLR sky all morning until we left road at 12:30. No avalanche activity was observed but the snow surface rapidly warming and MFc had broken down by 10:30 at 6100'. No visual obs of a few areas that we suspect may have avalanched - including Weeping Wall, Triple Arches, and Lower Slopes. Heaven's Peak Reminant Glacier and East Face glide cracks have released, presumed last evening.
