The Trinity Alps Giant Salamander: Something Big Beneath the Water

Frank Griffith had already found what he came looking for.

Sometime during the 1920s, the California attorney was hunting deer deep in the Trinity Alps when he stopped beside a small mountain lake near the headwaters of the New River. His hunt had apparently been successful, but something beneath the surface soon became considerably more interesting than the deer. There were salamanders in the water.

Very large salamanders.

Griffith later claimed that five of the animals were visible along the bottom of the lake. The smallest was perhaps five feet long. The largest approached nine! At some point Griffith reportedly managed to hook one. Whatever was on the other end of the line was too large for him to pull from the water, and the animal eventually escaped.

Then Griffith went home. For years, his encounter remained little more than an obscure story from an isolated corner of Northern California. Eventually, however, it reached people who knew quite a bit about salamanders. Some of them thought the story was ridiculous.

Others wondered whether Griffith might have seen something science hadn't found yet.

Deep in the Trinity Alps

The Trinity Alps rise from the mountains of Northern California, roughly between Redding and the Pacific Coast.

This isn't the California of beaches, palm trees and Los Angeles freeways. The region is rugged mountain wilderness filled with granite peaks, dense conifer forests, deep valleys, alpine lakes and cold streams. The Trinity Alps Wilderness alone encompasses hundreds of thousands of acres, and much of the terrain can only be reached on foot.

Water is everywhere. Snowmelt feeds clear mountain lakes and streams that eventually drain into the Trinity and Klamath river systems. Black bears, mountain lions, deer and other wildlife inhabit the surrounding forests, while rough-skinned newts and several species of salamander occupy the wetter corners of the ecosystem.

One of those amphibians is particularly important to our story.

The Pacific giant salamander is native to the Pacific Northwest, including Northern California. Despite the impressive name, it generally reaches only around a foot in length. That's a substantial salamander, but not something you're going to mistake for an alligator!

The remoteness of the Trinity Alps, highlighted in this 1973 US Dept of Interior study, has always been one of the strongest arguments made by believers in the cryptid. There are enough isolated lakes, creeks and inaccessible valleys to make the idea of an overlooked animal seem at least possible. The question isn't whether an undiscovered salamander could hide here.

It's whether one the size of a human could.

What Is the Trinity Alps Giant Salamander?

The Trinity Alps Giant Salamander is an alleged enormous amphibian reported from the lakes and waterways of Northern California.

Descriptions vary because sightings are rare, but the creatures are generally said to be:

• Approximately five to nine feet long

• Dark brown or greenish in coloration

• Sometimes marked with dull yellow spots

• Broad-bodied with four short legs

• Aquatic or semi-aquatic

• Similar in general appearance to known giant salamanders

Unlike the Enfield Horror or Flatwoods Monster, there is nothing particularly supernatural about its reported anatomy. It's basically a salamander... an absolutely enormous one.

That simplicity makes the creature unusually interesting from a cryptozoological standpoint because giant salamanders aren't imaginary animals. The Chinese and Japanese giant salamanders belong to an ancient family of amphibians whose members can reach extraordinary sizes. North America has its own member of that family, the Hellbender, although it is considerably smaller.

The idea of a very large aquatic salamander therefore doesn't require us to invent an entirely new kind of animal. This one is on the very fringes of plausibility... but theoretically possible.

The History of the Trinity Alps Giant Salamander

Most versions of the modern legend begin with Frank Griffith's encounter during the 1920s.

Years later, Griffith's story reached Thomas L. Rodgers, a biologist who took the reports seriously enough to investigate. Rodgers wondered whether an isolated population of Pacific giant salamanders might somehow have developed unusual size, or whether the Trinity Alps could conceivably harbor a relative of the enormous Asian salamanders.

In 1948, Rodgers made several trips into the region searching for evidence. He didn't find any giant salamanders, but he was inspired to follow up on another strange salamander story circulating in California.

In 1939, Stanford University ichthyologist George S. Myers examined an unusually large salamander caught in the Sacramento River. The specimen measured somewhere around 25 to 30 inches long and appeared similar to an Asian giant salamander. Rodgers decided to investigate the case and concluded that the animal was almost certainly an escaped imported Chinese giant salamander. A collector named Wong Hong had reportedly lost one from a container aboard a vessel in the Sacramento-San Joaquin river system.

So California really did have an enormous Asian salamander swimming around where it didn't belong. Unfortunately for our cryptid, it had an owner. However, the Trinity Alps reports continued.

One of the most dramatic came from animal handler Vern Harden, who claimed to have encountered a group of enormous salamanders at remote Hubbard Lake. In January 1960, Harden reportedly hooked one and estimated its length at an astonishing eight feet four inches. According to the story, worsening winter weather forced him to abandon the animal before it could be preserved or properly examined.

By this point, the story had attracted enough attention that serious researchers returned to the mountains. Rodgers participated in another search in 1960 along with noted herpetologist Robert Stebbins and zoologist Nathan Cohen. The expedition collected Pacific giant salamanders from the area, but nothing remotely approaching the reported size. The largest specimen was reportedly less than a foot long.

Rodgers eventually published a scientific discussion of the California giant salamander reports in the journal Copeia in 1962. His conclusion was decidedly skeptical (Scientists, right?). During the searches, he noted that people unfamiliar with the terrain sometimes mistook submerged branches and logs for giant salamanders.

The searches didn't completely end there. Cryptozoological expeditions continued sporadically, including a 1997 search led by Kyle Mizokami. Once again, no giant salamanders were found.

Nearly a century after Griffith's story, science still hasn't produced a specimen.

So, What Are People Seeing?

This is where the Trinity Alps Giant Salamander gets unusually interesting.

Let's start with the easiest explanation.

Logs.

A long dark object lying beneath the surface of a mountain lake can look remarkably organic, particularly through moving water. Rodgers himself reported people on expeditions mistaking submerged branches for salamanders. Add poor visibility, distance and expectation, and some sightings probably don't require an animal at all.

Known salamanders provide another possibility.

Pacific giant salamanders actually inhabit Northern California. Someone encountering an unusually large specimen could exaggerate its size, particularly when looking through water where refraction makes accurate measurements difficult.

But getting from roughly one foot to nine feet requires a lot of exaggeration.

The escaped Asian salamander examined in 1939 adds another intriguing wrinkle. We know at least one unusually large exotic salamander really was loose in California waterways. Could other imported specimens have escaped, been released... or... interbred to create a MUTANT SALAMANDER?

Possibly.

That explanation becomes much harder when applied to reports from remote mountain lakes and to stories allegedly predating widespread importation of such animals. Then there's the most exciting possibility: an unknown native species.

Giant salamanders once had a broader evolutionary history in North America, and the existence of the Hellbender demonstrates that enormous aquatic salamanders aren't biologically alien to this continent. A previously undocumented population living in isolated Northern California waterways isn't impossible in the same way that a glowing humanoid floating through the woods might be.

Amphibians leave evidence. A sustainable population should include adults, juveniles and dead animals. Researchers should eventually find eggs, larvae, bones, environmental DNA or specimens washed downstream. Multiple expeditions specifically searching for these animals have found none.

And nine feet is enormous. However, this is a VERY remote area and a small, isolated population may exist. As we always say at Oddageddon, "Improbable does not mean impossible."

The largest living salamanders known to science don't normally reach anything close to the biggest Trinity Alps estimates. A nine-foot animal would represent an extraordinary biological discovery requiring extraordinary evidence.

So far, we have stories. Very interesting stories, but stories nonetheless.

Our Take

This might be one of the most frustrating creatures in the Oddex.

Not because the Trinity Alps Giant Salamander is especially ridiculous, but because it isn't. And I want this one to be real SO badly!

If someone told us there was an undiscovered population of eight-foot salamanders living underneath a Walmart parking lot in Sacramento, we'd have some questions. OK, bad example, I have been in the bowels of many Walmarts... and I am convinced that some very creepy crap lives there! But I digress.

Place Giant Salamanders in remote mountain lakes surrounded by hundreds of thousands of acres of Northern California wilderness and the idea feels different. We already know giant salamanders exist. We know related amphibians live in North America. We know Pacific giant salamanders inhabit Northern California. We even know that at least one unusually large Asian salamander once escaped into California's river system. For a moment, all the pieces seem to line up.

Then we get to the evidence. Frank Griffith reportedly saw five animals but brought none back. Vern Harden supposedly hooked an eight-foot specimen but lost it. Scientists went looking and found ordinary salamanders. Later expeditions searched again and came home without evidence. That's a pattern the Oddex has encountered before.

Our guess is that the Trinity Alps legend grew from a mixture of genuine salamander encounters, submerged logs, mistakes in judging size through water and stories that became more impressive each time they were repeated. But we'd hesitate before stamping this one completely closed.

Species still turn up in places scientists haven't thoroughly surveyed, and remote aquatic environments are particularly good at hiding things. If someone eventually discovered a previously undocumented salamander in Northern California, the basic idea wouldn't overturn everything we know about biology. A nine-footer would be another matter.

Still, there's something appealing about hiking miles into the Trinity Alps, reaching a cold mountain lake and realizing that almost everything beneath the surface disappears after only a few feet.

Most likely, the biggest salamander down there would fit comfortably in your hands. But beware... there may also be a salamander that can comfortably fit YOUR HANDS in ITS MOUTH!

Hopefully.
