In this episode, Alex sits down with his uncle, geologist Dr. Robert Drake, to explore a career spent mapping the remote Andes, climbing 21,000-foot volcanoes, and helping reshape scientists' understanding of one of the world's great mountain ranges. They discuss Bob's expeditions with legendary volcanologist Wes Hildreth, the volcanic hazards they studied, and the discoveries that emerged from decades of fieldwork in Chile and Argentina. The conversation also reflects on the reunion Bob, Wes, and Judy Fierstein had planned to retrace their landmark 1984 expedition—a trip that never happened after Wes canceled at the last minute and passed away not long afterward. It's a story of scientific discovery, adventure, lifelong friendship, and the enduring legacy of one of the world's great volcanologists.
