Dubai, United Arab Emirates (CNN) – Ecuador’s largest waterfall appears to have disappeared after a sink hole swallowed part of its water source.
The San Rafael waterfall on the Coca River is a landmark in Ecuador and attracts tens of thousands of people every year, according to NASA.
Waterfall water was pouring 150 feet into a hole-like hole on the other side.
NASA indicated that the iconic waterfall has disappeared to be replaced by 3 water currents.
The site was closed to tourism activities and is no longer among the country’s tourism sites.
Ecuador’s Ministry of the Environment experts believe that the event took place at the source, in early February, diverting the current river course underground.
Soon after, technicians at the Ministry of Environment said they examined the waterfall and reported “possible damage to the river’s path, before the waterfall fell.”
However, technicians were unable to determine the exact cause at that time.
There is some ambiguity about whether the cause is a natural phenomenon, or from the construction of a hydroelectric generator on the river.
NASA said that the Ministry of Tourism does not intend to restore the path of the waterfall.
