“All over the world, people tell stories of strange ape-like creatures or wild men… [p. 4 – opening line] The first part of his book looks at some Bigfoot and yeti stories. The second part of the book uses science to ask questions about the evidence, to look at the theories, and to prove or disprove the existence of such creatures.” (p. 5)

There are 11 stories of sightings in the first part of the book. The sure number of  these sightings covered in this book makes this book superior to other books I’ve read on the topic. The sightings ranged from the west coast states of Washington, Oregon, and California, to Pennsylvania, then off to China , the Himalayas, to the Indus Valley. There is  a chart on page 39 of the number of recent sightings in 10 states with Oregon topping the list at 808 and Washington right behind it with 151 sightings.

As the book segues to the second half Charles Darwin’s “missing link” theory appears, as does a very brief cryptozoology statement. Some of the reasons given for not being able to prove or disprove Bigfoot’s or yeti existence include: they are ‘found’ in huge remote areas, most sightings of made by single individuals – without a second or third witness, there has not been an infrared camera photo of a Bigfoot or yeti, and low levels of oxygen at high elevations where they are found play tricks of people.

Then the book describes two hoaxes.

The book is not blatantly biased either way, the reader most make his/her own mind in the end.
