While researching his 2011 book Tracking the Man-beasts, he found a previously published catalogue of North American Sasquatch sightings. By organizing the sightings and their major characteristics into a continuum arranged by date and location, he was able to see patterns, and a fascinating theory emerged.
At first, the creatures showed enormous variation in color, height, behavior, foot size and even number of toes. To suggest a single undiscovered hominid living in the North American wilderness was one thing.
To suppose that dozens of different species existed, many of them in relatively populated places like Illinois and New jersey, "strains credulity," as Nickell put it.
