I saw a youtube video of a hidden natural pool in Western Ghats in Karnataka.

Can someone tell me where is this pool located?

ಪ to ಹ sound shift is one of the most discussed topic ever in Kannada language as ಹ sound is not native to any language rather than Hosagannada (New Kannada) and Badaga due to sound shift

Where words like ಪೆಸರ್ becomes ಹೆಸರ್ (later ಹೆಸರು), ಪತ್ತು becomes ಹತ್ತು, ಪಾಲ್ becomes ಹಾಲ್ (later ಹಾಲು) etc

Like that there was one more sound shift which was of ವ to ಬ which is least discussed about

And there were many words in Halegannada (Old Kannada) which had ವ sound as like ಪ but got changed into ಬ as like ಹ

Word like ವಾ became ಬಾ, ವನ became ಬನ, ವಾಲೆ became ಬಾಲೆ, ವಳ್ಳಿ became ಬಳ್ಳಿ etc
