  • Recent study revealed that the colour of water in Lonar Lake in Maharashtra is due to a large presence of the salt-loving Haloarchaea microbes.
  • Haloarchaea or halophilic archaea is a bacteria culture, which produces pink pigment, and found in water saturated with salt.
  • Absence of rain, less human interference and high temperature could have resulted in the evaporation of water, increasing salinity and pH levels in the lake.
  • Lonar Lake was created by a meteor impact during the Pleistocene Epoch.
  • It is the only known hyper velocity meteorite crater in basaltic rock anywhere on Earth.
  • It was notified as a National Geo-heritage Monument in 1979 by Geological Survey of India (GSI).

Verifying, please be patient.
