What is that pebble you’ve just picked up and what can it reveal about the story of the Earth?  Vojta Hybl is on a mission to help us identify the everyday rocks we find under our feet and to reveal their often remarkable stories. From helping amateur rock hounds – or just those out on a good walk – to identify the stones they come across, to aiding our understanding of the physical landscapes around us, he’s busy making geology accessible, fascinating and fun.
