Watersprite Lake weeke d

Sat we heard but did not see due to low vis what sounded like a rather large slide from somewhere on watersprite tower. Dig 2 pits, one sat and one sun. Both on 30 degree south face slope at approx 1600m. Produced easy planar fracture approx 30cm down on 3rd elbow tap. Because of this , large amount of recent snow and the avy we heard we played it safe and stayed out of the alpine. On the west facing lines we rode wr didnt observe any signs of instability.
