We observed several fresh avalanches in the Tony Grove area today.  Three avalanches on east and northeast facing slopes between 8500 and 9000 feet.   Two avalanches in Rocky Bowl and one on the east face of Mt Magog.  All three avalanches involved the new snow from Thursday night (top 4-8 inches) and did not step down into the snow from Wednesday and Thursday.   All three were similar in size 30-50 feet wide and ran several hundred feet.  All three started mid slope with no apparent triggers i.e. cornice fall, skiers, etc. 
 
We tested several steep (>35 degrees) north facing test slopes in the area and could not get anything to slide other than top sluff.  No other avalanches were noted.
 
We noticed a fairly significant melt/freeze layer on the southern half of the compass below 8000 feet.  The snow seemed to hold up better above that elevation.
