This was the question in the minds of people across India after Lake Lunar in Maharashtra changed shapes in recent days.
Experts believe the change is likely due to increased salinity in the water, the presence of algae or a combination of both – Like parts of Greater Salt Lake in Utah
or Lake Hillier, Australia
Gaganan Kharrat, the local geologist, said in a video posted on Maharashtra Tourism Twitter feed
That had happened before, but it wasn’t prominent.
“It looks particularly red this year because the salinity of the water this year has increased,” he said. “The amount of water in the lake decreased and the lake became shallow, so salinity rose and caused some internal changes.”
Kharrat said researchers were also investigating whether the presence of red algae had caused discoloration.
Samples are sent to several laboratories, he said, “Once studied, we will be able to tell conclusively why the lake water turned red.”
The lake, located about 500 kilometers (311 miles) east of Mumbai, was formed after a meteor collided with Earth about 50,000 years ago, According to its CNN News 18
. CNN News 18 reported that it is a popular tourist attraction and has been studied by scientists all over the world.
