The Man, The Myth, and The Legend of Grover Krantz

In the early 1990s in Sequim, Washington, on the heavily forested Olympic Peninsula, anthropologist Grover Krantz was building a helicopter to search for Sasquatch. He ordered the kit from some guy in the Midwest and spent several years trying to assemble it. He hoped the craft would provide the aerial view necessary to locate and retrieve a Bigfoot carcass.

“My attempt to build and fly an ultralight helicopter and use an infrared imager to locate a decaying body [of Sasquatch] so far has failed,” Krantz told a reporter in a TV interview. “I finally figured out what the problem was [with the helicopter assembly], but for three years now, I haven’t had the chance to correct the situation.”

He planned to make one last attempt in the summer, he said, and insisted no reporters be there for the flight. “I don’t want somebody photographing my bloody body as it’s dragged out of the wreckage,” Krantz said, only half-joking.

Until his death in 2002, Krantz was unwaveringly dedicated to the search for Bigfoot, and was willing to risk life, limb, and career to discover it. When a reporter asked Krantz what the likelihood was that Sasquatch existed, he replied without hesitation, “Guaranteed.”

So what exactly convinced Krantz, an anthropology professor at Washington State with two degrees from UC Berkeley, that Bigfoot was real?

It all started with a movie.

Though Krantz was mildly interested in anomalous primates since he was a teenager, it wasn’t until the 1960s when he saw the famous Patterson-Gimlin film—supposedly the first known footage of a Bigfoot walking through the woods near Bluff Creek in Humboldt County, California—that he took up the cause.

From Krantz’s point of view, the Patterson-Gimlin Bigfoot’s strides and arm movements weren’t easily mimicable by a human and could not be sustained for more than a few steps, which to Krantz, proved the film’s validity.

“The Patterson subject walks with the body leaning forward, and with the knees largely bent, so that when it takes a step, it supports the leg with a bent knee and keeps two feet on the ground for an unusual length of time,” Krantz told the Discovery Channel, demonstrating the stride by leaning forward and lifting his feet up high as if walking through mud. His tone was certain and his strut confident.

Later, Krantz would become even more convinced of Bigfoot’s genuineness with the discovery of “Cripplefoot,” a print found in Bossburg, Washington, a ghost town near the Canadian border. He studied casts of this print and donated copies of it to UC Berkeley’s Phoebe A. Hearst Museum of Anthropology, which displayed the casts in an exhibit on Darwin Day in 2008. What made this footprint different was that it appeared to be authentically deformed; to Krantz, the impression made in the dirt indicated that a truly heavy, crippled beast had left it, not a human hoaxer. Krantz decided that any person who could fake that footprint would have to be as educated as he was, something Krantz highly doubted.

“It has not yet been established that the Sasquatch exists,” Krantz wrote. “To pass laws against harming sasquatches presently makes little more sense than protecting unicorns.”

“If somebody faked that and put all of the subtle hints of the anatomy design in that, he had to be a real genius, an expert at anatomy, and very inventive and original in thinking,” Krantz said. “He had to outclass me in those areas, and I don’t think anybody outclasses me in those areas. At least not since Leonardo Da Vinci, and I’d say such a person is impossible and therefore the tracks were real.”

Later in his research, Krantz would go on to conclude that Bigfoot was likely Gigantopithecus, an extinct Asian primate that existed from perhaps nine million to one hundred thousand years ago. He thought they may have migrated to North America via the Bering Strait when it was still a land bridge. Though scientists have yet to discover a full fossil skeleton of the creature, Krantz examined a mandible and theorized that it walked upright, bipedally, and that it shared many characteristics with Sasquatch.

Of course, Krantz knew that his theories counted for nothing until he could produce irrefutable evidence in the form of a body… which is why he’d spend many a night cruising the Washington backroads alone with a spotlight and a shotgun. This made him unpopular among many cryptozoologists, amateur researchers who study and search for animals described in legend and folklore.

Krantz’s plan to kill a Bigfoot “was a political hot potato,” said Idaho State University anatomy and anthropology professor Jeffrey Meldrum, a colleague of Krantz’s who continues the search for Sasquatch. “It divided the Bigfoot community right down the middle with strong feelings on both sides.”

If Bigfoot were a real creature and if Krantz were to shoot one, he might be helping to kill off the species for the sake of his own research, something many Bigfoot believers find unconscionable, Meldrum explained. But Krantz’s point was that no one would bother to preserve the species until it was recognized by science, which is why he was determined to bring in a corpse.

“It has not yet been established that the Sasquatch exists,” Krantz wrote in his book The Scientist Looks at Sasquatch. “To pass laws against harming sasquatches presently makes little more sense than protecting unicorns.”

“I wrestled with the issue mentally and ethically and so forth for a long time,” said Meldrum, who eventually took the opposing position, deciding it was wrong to kill one no matter what the circumstance. “But I’m not passing judgment on Grover for that.”

Though Krantz never found a Bigfoot dead or alive, he had what he thought were close calls.

Though Krantz would have preferred to find a specimen that died of natural causes, he knew the likelihood of that was slim to none. It’s actually difficult to find remains of any species, Krantz explained in The Scientist Looks at Sasquatch, partly because remains are usually carried off by other creatures for sustenance.

Still, Krantz thought it was possible.

In fact, many species that were formerly thought to be fixtures of mythology have been found among us, including giant squid, manatees, and mountain gorillas. These discoveries help explain why a growing number of modern scientists and academics think that cryptozoology, though often dismissed as pseudoscience, deserves more respect.

“Cryptozoology is really the study of those things that lead up to the discovery and verification of a creature. For instance, the mountain gorilla which was reported and seen and talked about in folklore for hundreds of years was not verified as animal until 1901,” said author and cryptozoologist Loren Coleman, a friend of Krantz, in an interview with Radio New Zealand. “It took scientists over 60 years of tracking the first giant panda before they discovered it. And Bigfoot has really only been pursued, and not even by scientists…for just 50 years.”

Though Krantz never found a Bigfoot dead or alive, he had what he thought were close calls. Once, returning from an expedition with students in central Washington, Krantz was driving through a snowstorm when something large and brown loped quickly across the road, causing Krantz to slam on the brakes, said Krantz’s former student, archeologist and physical anthropologist Gary Breschini. The group piled out of their vehicle and started tracking the creature with vigor, until someone finally asked: “What are we doing in a snowstorm tracking something that might be 800 pounds? And what do we do if we catch it?” They gave up the search, disappointed yet exhilarated.

Breschini said that even though Krantz made his share of enemies in Washington State’s anthropology department, his students adored him. He made friends with them and was always game to hang out and chat over lunch—which for him usually consisted of a cigarette, a cup of coffee, and two chocolate donuts. He pushed his students to be original in their thinking, Breschini said, and to challenge commonly held ideas.

“We were free to come up with ideas that were contrary to what everyone else was coming up with,” Breschini said. “He let us think outside the box, and the nice thing about it was, he made us defend our attempts to think outside the box.”

Krantz was also seen as a maverick when it came to his research methods, Meldrum said, which made him funny and entertaining. One year, Krantz molded a set of heavy brow ridges and strapped them to his head, Meldrum explained, so he had on what looked like a fleshy sun visor. He let his hair grow out all summer with the professed intent of trying to ascertain the advantage of a hominid’s having such ridges.

“He came to the conclusion that it kept the hair out of your eyes,” Meldrum said. His theory was that once hominids started growing longer head hair, they couldn’t figure out how to tie it behind their head or put a headband on, so there was strong selection for these heavy brow ridges to keep the hair out of their eyes. Meldrum thinks Krantz probably wore the visor as a big joke and that his wry sense of humor was often lost on some people.

“I spent enough time with him that I got a sense of his humor and wittiness. People would go, ‘Oh, he’s so arrogant,’” Meldrum said. “I was like, you guys just don’t know him.”

While Krantz may have been eccentric, he was also a respected scholar who made legitimate contributions to science. He was the first person to explain the function of the mastoid process; he proved that Ramapithecus, an extinct primate genus, was not ancestral to humans; and he was a pivotal figure in the case of Kennewick Man, which involved 8,400-year-old skeletal remains found on the banks of the Columbia River in 1996.

“The basic reason why some of the [Washington State] faculty didn’t support [Grover Krantz]… was not so much because of Bigfoot, but because he stayed with it when his evidence never got any better.”

He was also undeniably intelligent, a member of both MENSA and INTERTEL, high IQ societies. In fact, some say he was too smart for his own good.

“In some respects he was so far ahead of other people,” said Breschini. And he wasn’t afraid of letting everybody know. Breschini recalled one paper Krantz submitted for publication that never made it to the presses. Not because it was a bad paper, but because Krantz was the only source.

“He essentially had no references. He said, “It’s all my thinking and it’s all new, so why should I refer to somebody else?’” Breschini said. “It stems from his knowledge and understanding of the subject; he didn’t feel like he needed to do things the traditional way, because he came up with a new way.”

Which rubbed some people the wrong way.

Krantz’s interest in Bigfoot was a touchy subject for the anthropology department at Washington State, which, according to Krantz, was why he was always turned down for promotions and grants. But Donald Tyler, a former student of Krantz’s and a professor of anthropology and sociology at the University of Idaho, said it was more nuanced than that.

“The basic reason why some of the faculty didn’t support him for full professor was not so much because of Bigfoot, but because he stayed with it when his evidence never got any better,” Tyler said. It was also common knowledge that Krantz fell prey to hoaxes.

Tyler himself was able to deceive Krantz. After graduating, he and another professor made a fake Sasquatch cast and took it to Krantz for analysis. To make the cast, they made an imprint in the ground, filled it with plaster, and used their fingers and foreheads to create lines in the bottom of the cast. Upon examining it, Krantz determined, based on specific dermal ridges and lines in the foot, that the cast was without a doubt from the Blue Mountains.

“Before it became unbearable I told him that we made that track,” Tyler said. “He didn’t get angry or anything, but what I was trying to do…was show him how things can be faked and how the people he trusted were faking it.”

Krantz was undeterred however. Just because some evidence is fake, doesn’t mean all the evidence is fake. Because footprints have been found for so many decades in so many different places in the world, it seemed completely implausible to Krantz that every one of them could have been faked.

“The fakery must have been designed by a brilliant human anatomist at least 40 years ago, and one who has ever since been directing a large group of people placing thousands of these tracks under remarkable circumstances, and all this without even being seen or having a member expose this colossal hoax,” Krantz wrote in The Scientist Looks at Sasquatch.

Krantz thought he was right and that he had evidence worth pursuing, Breschini said, and that’s the way great discoveries and innovations come to be. That he never found proof is largely beside the point.

“Science works on evidence and hypothesis and theory,” Breschini said, but the commonly held idea during Krantz’s time as professor was that Bigfoot was impossible. Few academics would even consider the evidence. “That’s not a very scientific approach, but that’s unfortunately what some folks felt.”

To an extent, Krantz knew how crazy his belief in Sasquatch seemed to people, but he found it even more absurd that Bigfoot might not exist. “The way I like to put it is, Sasquatch is ridiculous. But the alternative of a hoaxer is impossible. Therefore—the ridiculous must be true.”
