At least 6 killed after rock falls into Brazilian lake

A towering slab of rock broke from a cliff and fell onto pleasure boaters near a waterfall in Brazil on Saturday, and officials said at least six people died. As many as 20 people are thought to be missing.  Officials said at least 32 people were injured, though most had been released from hospitals by Saturday evening.

Footage showed a gathering of small boats moving slowly near the sheer rock cliff on Furnas Lake when a fissure appeared in the rock and a huge slab toppled onto at least two of the vessels. Furnas Lake is a popular tourist draw roughly 420 kilometers north of Sao Paulo.  It's believed the rock fall could have been the result of recent heavy rain.
