Dragline work to lower the outlet channel of Earthquake Lake on October 18, 1959. The tripod on the hill at center left is one of five lighting plants that allowed nighttime work. Note the “bathtub ring” of killed trees along the shoreline marking the high stand of Earthquake Lake before lowering of the outlet channel. Photo by Mrs. Steven W. Nile (Dr.

An ash plume rises from the summit crater of Parícutin sometime during 1946-48. A thick ash deposit covers the foreground. An estimated 4,500 cattle and 550 horses died during the heavy ashfall in the early months of the eruption, devastating the local people who depended on the animals for food, plowing, and transportation.
