Discovery and Excavation of the Lindsay Mammoth in Montana, 1967 

In July of 1967 in far eastern Lindsay Montana, dryland farmer Joe Walker was running his combine along a Dawson County road when he spied some white, chalky material weathering out of the borrow pit. Upon closer examination, he was stunned by its size and thought that it looked like pieces of a fossilized elephant tusk.
News of the find made its way to Montana State University in Bozeman, and young PhD candidate Les Davis was hired to direct the Lindsay Mammoth recovery project. Over 30 hot days in July and August, Davis and six students painstakingly uncovered the massive mammoth grave.
