Explanation:

The Lonar lake was first mentioned in ancient scriptures such as the Skanda Purana and the Padma Purana. The Ain-i-Akbari, a document written about 1600 CE, states: These mountains produce all the requisites for making glass and soap. And here are saltpetre works which yield a considerable revenue to the State, from the duties collected. On these mountains is a spring of salt water, but the water from the centre and the edges is perfectly fresh.
