Rock Face?

Walking up the steep path to the Edakkal Caves, I stopped for a while to catch my breath, and leaned against this huge rock - one of many such along the path. 


"Amma, it looks like a face" said Samhith, and I wondered what he was talking about. It was only when I heaved myself up that I was struck by the look of the rock I had been leaning against! It did look like a face.... in fact, to me, it looked a bit like a gorilla! A throwback to the ancestors who left their mark behind on the caves? What do you think?
