To Harris' credit, he edited his story after I wrote about the artificial origin of the "devil" statue. The tale remains on the GAWM website to this day, however, serving as evidence not of the Nephilim but of what happens when you are so in love with an idea that you can't even bear to shine the dimmest critical light on your heap of "evidence." Just look at the thing:
With Harris' rejection of the Devil, membership in the Fan Club was down to one. It is with regret but not surprise, however, that I report to you that membership is up: the account of the Helenwood Devil is, once again, put forth as "evidence" for whatever it is that Fritz Zimmerman is talking about in his 2015 book The Encyclopedia of Ancient Giants in North America. The book, which appears to be yet another uncritical cut-and-paste compilation of media accounts marketed as "research," includes the Helenwood Devil in the chapter titled "Giant Humans With Horns" (pg. 295). Either Zimmerman didn't do the basic research necessary to discover that the Helenwood Devil was actually a clay statue, or he doesn't care. I'm not sure which is worse, and I'm not sure it matters. Uncritically presenting the Helenwood Devil account as "evidence" for anything is, in my opinion, a self-evident demonstration of an extreme disinterest in the process or outcomes of research. That's as nicely as I can put it.
Here's another post about how the inability or unwillingness to use whatever tools are available to discriminate between credible and non-credible evidence is symptomatic of pseudo-science in general.
On a related note, L. A. Marzulli vouches for Zimmerman's abilities in the forward (sic) to the Encyclopedia, stating that Zimmerman is a "champion of the truth" and a "class A researcher." So there you go.
