"[Heavy Ground] does something unexpected. It opens a new perspective onto William Mulholland... [bringing him] to life in all his sharp-elbowed, stubborn glory, saddened and perplexed by the St. Francis Dam debacle yet prideful until the end."
—Wall Street Journal

“A meticulously researched… case study of the catastrophic failure north of Los Angeles in March 1928 of the St. Francis Dam that killed 400-450 people… [Heavy Ground] is exemplary for its use of previously unavailable original sources, particularly the L.A. Coroner’s Inquest report.”
 —Pacific Historical Review
 
“A gripping account of this ill-fated dam and the person most directly responsible for its flawed design: William Mulholland.”
—Technology and Culture
 
"Carefully-crafted, exhaustively-researched, liberally-illustrated, and engagingly-written... an important and welcome addition to the pantheon of scholarship on California Water History."
—Southern California Quarterly
 
 “Above all, [Hundley and Jackson] tell the story of the tragedy itself, the testimonies and recollections of survivors, the arguments over reparations for property damage and lives lost. Forget about Chinatown. This book sets a standard for scholarship that scholars will have to meet in their own research into Los Angeles’ controversial water history.”
—Western Historical Quarterly

 “For its lucid explanation of the politics surrounding the [St. Francis] disaster, its minute-by-minute description of the dam’s final moments, and ensuing tidal wave that murderously swept down the valley, and its meticulous and careful analysis of the dam’s design, construction, and failure, Heavy Ground joins the list of [Hacker Prize] books displaying “exceptional scholarship” while reaching for readers “beyond the academy.” Additionally, the book superbly integrates the history of technology with social, cultural, and economic contexts.”
