Surrounded by lush vegetation and rare butterflies, the San Rafael Waterfall was one of the most captivating landscapes in Ecuador.
With water dropping 150 meters (490 feet), the river and falls cut through a thick patch of cloud forest at the intersection of the Andes Mountains and the Amazon Basin.
As the country’s tallest waterfall, it attracted tens of thousands of visitors per year.
But now, the cascade has disappeared. It stopped flowing on February 2, 2020. The video below shows the exact moment when the sinkhole forms:
and just after the waterfall ran dry:
These images were acquired by the Operational Land Imager (OLI) on Landsat 8. The image below shows a photograph of the falls on November 28, 2012.
According to media reports, a huge sinkhole appeared in the Coca River a few meters before the falls and diverted the watercourse.
Now, the water falls in three separate sections and at a less steep slope, which cannot be seen from viewing stations located around the original waterfall.
Researchers believe the three streams could cause erosion at the channel’s origin and create a river upstream, which might change the topography of the valley.
The cause of the sinkhole is under investigation
No matter the cause, Ecuador’s tourism ministry does not plan to reconstruct the riverbed or restore San Rafael. The waterfall is now part of history.
But it’s not the only waterfall to have disappeared underground. The Devil’s Kettle Waterfalls in Minnesota has kept folks baffled as to where all the water goes. Another famous waterfall mysteriously disappeared OVERNIGHT in Chiapas, Mexico.
