Novarupta, 1912

The eruption broke out from a new vent on 6 June, and the plinian column jetted skyward with little interruption for 60 hours. Hot ash filled what came to be called the Valley of Ten Thousand Smokes, and the fallout spread downwind exceeded that of all other historical Alaskan eruptions combined. Most of the magma had been stored beneath Mount Katmai 10 km away, which collapsed as the eruption drained it, a relationship established by Curtis's later fieldwork.
