Query: Absolute drivel!

I waited until Mars Global Surveyor had returned high-resolution images of this area of the planet Mars before I turned to this book, and I can say in all honesty that it is a very long time indeed since I came across such absolute drivel. It isn't just the 'face', it's all the structures which he imagines to be around its location, building it up into some sort of metropolis, that is so stupid. If you want a laugh, go buy it. If you want to find out about Mars, buy something else.David Harland
