Best known for a vivid account of the 1959 Montana-Yellowstone earthquake, this writer turned a dramatic real-life disaster into a clear, gripping narrative. Very little biographical information appears to be readily available, which gives the surviving work an added sense of mystery.

by Edmund Christopherson
Project Gutenberg lists Edmund Christopherson as the author of The Night the Mountain Fell: The Story of the Montana-Yellowstone Earthquake, a nonfiction book about the devastating August 17, 1959 earthquake in the West Yellowstone area. The work has also been recorded for LibriVox, which suggests it has continued to find readers long after its original publication.
Reliable biographical details about Christopherson are scarce in the sources I could confirm here. Because of that, it is safest to remember him through the book itself: a factual, accessible telling of a major natural disaster that affected Montana and Yellowstone visitors alike.
