Ebook: The Night The Mountain Fell: The Story of the Montana-Yellowstone Earthquake

This is an informative and gripping account of the 1959 Hebgen Lake earthquake, also known as the 1959 Yellowstone earthquake, which struck in southwestern Montana on August 17 at 11:37 pm (MST). The earthquake measured 7.3-7.5 on the Richter magnitude scale and caused a huge landslide, leaving 28 people dead and causing US $11 million (1959) in damage. The slide blocked the flow of the Madison River resulting in the creation of Quake Lake, and effects of the earthquake were also felt in Idaho and Wyoming. It was the strongest and deadliest earthquake to hit Montana since the 1935-36 Helena earthquakes and caused the worst landslides in the history of the Northwestern United States since 1927. With numerous illustrations and color photographs, and eyewitness accounts help to tell the story.
