Alan Willendrup’s previously published book, The Lassen Peak Eruptions and Their Lingering Legacy, has been completely revised and expanded to include photos, many never published before.


The 1914-15 eruptions received sensational and very exaggerated national coverage. This book sets the story straight. In 1975, Alan interviewed many eyewitnesses to the eruptions who were still alive and graciously shared their accounts with him. Their vivid recollections of this geological milestone brought this narrative to life: they are the real “meat and potatoes” of the book.


This book concentrates on the human-interest stories at the time: Lance Graham’s near fatal encounter during one of the momentous eruptions, Elmer Sorahan’s mad dash at night through the Hat Creek Valley to warn residents of the impending mudflow, B. F. Loomis and his now famous photographs of Lassen, and the effects the blasts and mudflows had on the families living in the immediate area of devastation.


These men and women are gone now, but their spirits and memories live on in the pages of this book.
