A large earthquake leaves clues of its nature that can be interpreted only by a diverse group of scientists. We cannot hope to form a coherent picture of the Borah Peak shock, a rare Great Basin event, without listening to each other and reflecting on the historical and geological record of its antecedents. At a workshop held less than a year after the Borah Peak mainshock we shared our observations, exchanged ideas, and revisited the spectacular landforms at the earthquake site. In the forty reports of this volume we present our findings, a wealth of preliminary, but interdisciplinary research.
