- The area around the lake is an eco-sensitive zone as it consists of the Ejecta Blanket that is made up of the same material as that found on the moon.
- The lake is a National Geo-Heritage monument.
National Geo-Heritage Monument
- The National Geo-Heritage Monument are areas of national importance and are notified under Geological Survey of India for protection, maintenance, promotion and enhancement of geotourism.
- There are 34 National Geo-Heritage Monuments in India.
- The respective state governments are responsible to protect these sites.
Why did the lake turn pink?
- Experts believe that the Lonar lake turned pink due to increased salinity in the water and also due to the presence of algae.
- The amount of water in the lake has reduced thereby increasing its salinity and turning the lake pink.
