746 Robert F. Griggs + A Society Expedition Camps on Baked Mountain in the Valley of Ten Thousand Smokes Prior to June, 1912, this was a fertile green valley. Then vents in the floor burst open and shot forth a river of incandescent sand, burying the valley many feet deep. Tens of thousands of fumaroles still smoked when Dr. Robert F. Griggs, leader of five National Geographic expeditions, discovered it four years later. Today only seven large ones remain active (page 749). Camp above served as headquarters for the 1919 expedition. The Society's flag flies beneath the Stars and Stripes. Glaciers cover the flanks of Martin Mountain in the background. ' As Dr. Griggs first saw the Valley of Ten Thousand Smokes: "It was as though all the steam engines in the world, assembled together, had popped their safety valves at once and were letting off surplus steam in concert."
