Freak accident-we've hiked this trail many times without incident. Speculation is that frost heaving was the culprit. There's still snow at that elevation.
"FRANCONIA, NH – A hiker climbing up Mount Lafayette yesterday afternoon was killed in a freak accident, when a huge boulder crashed from its perch and struck her.
Shu Qin, 28, of Shanghai, China, was staying with friends in Wellesley, Mass., and they were hiking up the Falling Waters trail in Franconia Notch, according to Fish and Game Lt. Todd Bogardus."

And here is one of the waterfalls they were hiking up to see, and where the accident apparently happened:
