Despite the fact that this book was written over 60 years ago, the information, research and scholarship that is demonstrated in this book is probably still just as valid today, as when it was written in 1961. People were probably more open minded on the subject back then, when explorers began encountering these creatures in their Himalayan treks.
Sanderson approaches the subject of ABSMs/Bigfoot/hominids in a very scientific, open-minded and non-dogmatic manner. Ivan T Sanderson comes from a zoological-botanical background and has travelled extensively around the world, visiting many of the areas where ABSMs have been encountered. His extensive knowledge of wildlife is put to good use in this book, and there are many instances where he was able to identify a given sighting of the ABSM as a known creature. But likewise, he was quick to shoot-down any ill-considered debunking of an encounter. His writing style is at times journalistic (especially in the opening chapters) but later moving to a more scientific style; so much so that I had to read through the last few chapters very slowly. The book is loaded with photographs, diagrams and especially maps, the latter of which Sanderson puts to good use in elaborating many of his ideas and theories.
His coverage of the subject is not limited to Northern India, Nepal, Tibet and the Himalayas. There is ample discussion of sightings/experiences with these creatures in South America, Africa, Central Asia and of course North America. My one criticism of his book is that he doesn't cover Australia. Is it possible that he wasn't aware of sightings, tracks and other evidence from Down-Under - the famous Yowie - with recorded sightings going back to the 19th century, not to mention the experiences of indigenous people for hundreds and thousands of years.
I learned so much from Sanderson's book. For example:
- When the different sightings and tracks are taken into account, there may be as many as 3-4 different species.
- Local lore, legends and mythology tie very closely with the areas/regions in which these creatures have been encountered.
- Sanderson found that there was a commonality to the type of vegetation and terrain in which the ABSMs have been encountered. The regions in which these creatures appear to inhabit are what he refers to as Montane forests. These are typically areas which are densely forested, not frequented or lived in by many humans and largely unexplored. It's surprising how much of the Earth's land surface is not frequented by human beings.
