Rocky has been collecting rocks since before the Himalayas existed. A lion of few words but immense geological knowledge, Rocky spent 40 million years observing the formation of mountain ranges, the opening of ocean basins, and the slow patient work of erosion. Rocky now channels all of that first-hand experience into hosting Deep Earth for the Tweens 9–12 audience — a show that treats geology as what it actually is: the biography of the planet, written in stone, over time scales that make human history look like a brief footnote.
