His arguments are objective and relevent - his conclusions are intelligent and logical. With Tonnies' book you will take a revealing trip to Mars - and you will go first class!"
- Peter Gersten
Mac and I had our disagreements about Martian artifacts. I once devoted a whole website - The House of Spirits - to my "findings" at Gusev Crater, two elements of which appear above from Sol 60 and Sol 136 respectively. (courtesy of JPL/NASA) Mac was not entirely convinced by my findings... but we were both devoted Martian enthusiasts and made a pact to "return" as future Martian archeologists!
His book, "After the Martian Apocalypse" is still available from Amazon.
