Down the Great Unknown: John Wesley Powell's 1869 Journey of Discovery and

Very descriptive and imaginatively written account.These crazy dudes gave all in the name of discovery and science,some gave their lives. What I really liked about this book was the authorsbackground narrative, e.g. The civil war and the horror of the lack of anaesthetic,plus his ability to make the science of geology sound exciting.I left this book with much more than the feeling of a great rollercoaster rideand would recommend it to the readers of adventure yarns, historicalscience and Western pioneer enthusiasts.

After watching Dan Snow's excellent BBC documentary on his teams expedition following Powell's original journey of discovery in 1869 I decided to read up a bit more on the subject in depth. This book is well researched and I found it to be a very interesting follow up to the two TV programmes.

Exciting and informative non-fiction account of the first people to take a boat all the way through the Grand Canyon, with lots of contextual information and input from modern boatmen and women. Has certainly 'wetted' (sorry) my appetite for my forthcoming rafting trip!

Good book about a great boating adventure. Easy read.

Bought for husband as he had just completed a trip through the Colorado river. So he thought it was very good.
