SUPERVOLCANO – in remembrance

So today would have been my dad’s 76 birthday. He and I wrote a book together a few years back called “SUPERVOLCANO: THE CATASTROPHIC EVENT THAT CHANGED THE COURSE OF HUMAN HISTORY.” After he passed away three years ago of ALS, I revised and updated the book. I wish we could have written more together. I miss my dad, but his work lives on. The book is available in print and in all digital formats.
