Large collapse at Maid of the Mist

From email: "At approximately 8600", east of Maid of the Mist Creek, I started skinning from the tree edge slightly into the north-east facing meadow. Immediately after leaving tree-line, I heard a large "whump" and noticed a faint crack that shot far into the meadow (I could only see it for 20-30 feet it was so faint, and did not show up in my photo, but it is likely it went farther from how loud the collapse was). We decided to turn around there and carefully re-traced our tracks back into the safety of the dense forest and descend back to our cars that route."
