Ecuador waterfall disappears

San Rafael Waterfall, at nearly 490 feet the highest waterfall in Ecuador, disappeared in late February after the Coca River, which fed it, diverted into a sinkhole upstream believed to have been created by a series of landslides earlier in the month. Naturalists do not believe the waterfall will return naturally. It was a centerpiece of the Cayambe-Coca Ecological Reserve, a national park in the Amazon rainforest.
