Trace Unknown
by Barbara Ann Campbell
Bigfoot, an unknown species of animal, would be able to survive in the same environment, living off the same food sources as known species in the target area.
The animal's activities would bare striking resemblance to the grizzly bear, black bear, cougar, wolves, ungulates and porcupine. Perhaps that would explain some of how it has managed to have eluded our attention.
Inside, Barb has compiled an extensive profile on Bigfoot and shares her discoveries of the first year of operations. This book is reference material for the serious Bigfoot field researcher. Campbell is a former UFO and paranormal researcher.
She has also served as a forensic investigator of unexplained animal deaths (UAD), aka animal mutilation cases, and has appeared on Cattle Killers episode of MonsterQuest.
