A recent scientific discovery in Washington State suggests that areas in North America once harbored large colonies of giant, man-sized rodents — distant cousins to today’s prairie dogs.

In late 2024, while searching for ancient dinosaur fossils, a field team of Princeton University paleontologists has uncovered a startling find — the skull of a massive prehistoric rodent, along with other skeletal remains.

The skull, nearly the size of a horse’s head, is almost identical in form to the skull of a modern-era prairie dog, though it is is more than 50 times as large. Apparently today’s Black-Tailed Prairie Dogs had some very large predecessors. Based on the size of the skull and other bones, scientists estimate that the giant prairie dogs could stand up to 7′ tall and weigh up to 350 pounds. In other words, this critter was man-sized.

The giant rodents lived much like modern prairie dogs do today — grazing on vegetation and nesting underground in burrows. The giant skull was unearthed in Washington’s Mima Mounds Natural Area Preserve. View More: Mima Mounds Aerial photo.

Mystery of Mima Mounds Finally Solved
Southwest of Seattle, near Littlerock, Washington, you’ll find the Mima Mounds, a vast field of clustered earthen mounds covering over 600 acres. Since their discovery (by whites) in the 18th century, the Mima Mounds have confounded scientific explanation — until now that is. The location of the giant prairie dog skull and bones inside one of the Mima Mounds indicates, with great certainty, that the mound field was created by a large colony of giant burrowing rodents. Scientists now believe that the Mima Mounds area is a prehistoric prairie dog field, created by the creatures scientists have nicknamed “Big Dogs”.

NW Indian Legends Spoke of Giant Prairie Dogs
The presence of the giant prairie dogs at Mima Mounds is confirmed by Northwestern Indian legends describing a giant burrowing beast that stood as tall as a man, when raised on its hind legs. Researchers, who transcribed oral histories of the Sauk-Suiattle tribe, have recorded numerous references to a large, man-sized creature that burrowed underground. In the Suiattle language the beast was called “Chok-lahtle-wachook”, which, literally translated, means “Standing Man-Mouse”. A number of ancient Indian carvings and artifacts have depicted this creature (see photo at right), but cultural historians had not understood their significance. For decades the historians presumed Chok-lahtle-wachook was a wholly fictional man-beast, not a real species. Such mythical hybrid creatures are commonly revered as important totemic spirits by many Native American cultures. However, it now appears that Chok-lahtle-wachook really existed, and did so in great numbers.

Can Science Revive the Giant Prairie Dog?
The discovery of the giant prairie dog has electrified the scientific community because it appears that bone samples may contain recoverable DNA. And that means — you guessed it — there is a small chance that Chok-lahtle-wachook could be cloned. Geneticist Amy Moorwall of the Univ. of Washington explains: “These are not 100-million-year-old dinosaur bones. This creature lived in relatively recent times, so there is much more genetic material remaining that hasn’t completely fossilized. Initial inspection of bone marrow samples suggest that there may be viable, complete DNA strands that could be recovered. If that’s true, this could be one of our first opportunities to revive an extinct species.”

Varmint Hunters Hope for Successful Cloning
Could Chok-lahtle-wachook once again stand tall upon America’s prairies through the application of modern genetic cloning technology? If so, that would be exciting news for the nation’s hunting community. Varmint hunting is hugely popular in North America, and the possibility of bagging a man-sized prairie dog would be a dream come true for avid varminters. Ryan Stanley of the Varmint Hunters’ Association (VHA) told us that his members hope that the giant prairie dog could be cloned successfully: “We would definitely support a cloning effort. Many of our members spend countless days, over many seasons, trying to earn a 1000-yard patch, signifying a confirmed varmint kill at 1000 yards. Getting that patch, for a varminter, is like a baseball player making it into Cooperstown. Needless to say, if VHA members have a chance to shoot at a 7-foot-tall, 300-pound varmint, instead of a puny little prairie dog, many more of our members will finally earn their 1000-yard patch.”

Never had a chance to hunt prairie dogs in the American west? Then check out this video. Dan Eigen, host of the We Love It Outdoors Television series, ventured to South Dakota for some varmint hunting. Dan teamed up with Varmint Hunter Association President Jeff Rheborg to patrol some South Dakota Dogtowns where things get serious. In the video, you’ll see p-dog hits at distances from 70 yards to roughly 450 yards. The hunters were shooting from portable, wood-topped swivel rests, using AR-platform rifles on X-type sandbag rest. (Rifle zeroing session is shown at the 5:30+ mark.)

Multiple cameras were employed so you can see both the shooter’s POV and close-ups of the prairie dogs downrange. Watch the shooters having fun with a prairie dog cut-out and some Tannerite at the 9:00-minute mark. This guys are having a grand old time sending critters to Prairie Dog Heaven — we think you’ll enjoy the video.

The 17 Winchester Super Magnum Rimfire (aka Win Super Mag or WSM) is the fastest, most potent modern rimfire round you can buy. This cartridge, which uses a modified nail gun casing, drives 20gr bullets at 3000 fps. The 17 WSM offers superior ballistics to all .22 rimfires, and is a clear step ahead of the 17 HMR. That makes this round a potential “game-changer” in the varmint fields. To guage the capabilities of the 17 WSM, Varminter.com tested the cartridge in the new Ruger 77/17 bolt-action rifle. Click HERE for Varminter.com Ruger 77/17, 17 WSM Review.

17 WSM shoots faster than the 17 HMR, so the 20gr bullets don’t drift as much in the wind:

Varminter.com reports: “The much-anticipated Ruger 77/17 chambered in the 17 Winchester Super Magnum (17WSM) has been released. Our Review Editor, William Chambers, put it through a full range test with all four currently-available ammunition loads. Afterwards, he took it on a short groundhog hunt[.] We put a lot of rounds through the guns we test, at targets, through chronographs and out in the field. This report includes all currently available 17 WSM ammunition and a sneak peek of the really nice Nikon Prostaff 5 riflescope.” READ REVIEW.

As part of its review, Varminter.com tested four different types of 17 WSM ammo for accuracy: American Eagle (20gr V-Max); Hornady (20gr V-Max), Winchester HV (20gr V-Max); Winchester HE (25gr V-Max). In the little Ruger, which suffered from a very heavy trigger, the most accurate ammo, by far, was the American Eagle, with an average 5-shot group size of 1.135 MOA at 100 yards. The Winchester HV was the worst, with a 2.304 MOA average for three, 5-shot groups. CLICK HERE for full accuracy test results.

After accuracy testing, Varminter.com Review Editor Chambers took the Ruger 77/17 on a Groundhog hunt in Northern Ohio. Chambers was successful, bagging this ‘hog’ at 127 yards. The American Eagle 17 WSM ammo did quick work — the groundhog dropped without a twitch (watch video).

Overall, Chambers was impressed with the Ruger 77/17 in 17 WSM: “Although the rifle is pricey in the $700 to $730 range, it is a well-built rifle with everything you would expect from Ruger. The rifle functions flawlessly. There are no issues with the magazine, rounds chamber and empties eject with no problems. The trigger is crisp, but is so heavy that, in our opinion, it affects the rifle’s accuracy. We wish that a $700 to $730 rifle would come with a better trigger, because at some point, the factory trigger will need to be worked on, or replaced[.]”

Sample Varmint Hunter Magazine Back Issues

This year, according to VHA President Jeff Rheborg, the Jamboree has been cancelled for financial reasons. In addition, “all shooting events will be suspended for the 2012 shooting year at the VHA range”. On Friday, May 4th, Jeff issued this statement:

RE: 2012 Shooting Events

I hope this letter finds you enjoying the spring weather many are having. With much regret, all shooting events will be suspended for the 2012 shooting year at the VHA Range. With the uncontrollable events of last year and the financial loss we incurred, we feel the overall cost of repairing, maintaining and preparing for these events is not financially viable for this year. The foundation of VHA is stable; we feel it necessary to protect it in this uncertain economy. If you were registered for the 2011 Jamboree your refund will be forthcoming.

We apologize for any inconveniences this may cause. Thank you for your continued support!

Jeff Rheborg

To all VHA Members and Supporters:

With a heavy mind and heart we regret to inform you that we will not be hosting the 2011 Annual Jamboree. Some of you may already know and some might not have yet heard; the communities of Pierre and Fort Pierre are currently undergoing a flood. Each city has a levee system running parallel to the Missouri River, with some even running through the middle of town. Water currently being released from Lake Oahe is at 150,000 cubic feet per second. It is projected to stay at that level through mid August. To make it easier to visualize… if you were eating supper at the Pizza Ranch and looking out the window, if the levee was not there, all you would see is water. It is that high.

We did not reach this decision lightly. We took into account information we have received from local, state and national authorities as well as a long list of variables such as: electricity availability, water lines that may be affected, and the hundreds of evacuees that are being housed in area hotels. While we value the opportunity our annual Jamboree has to bring in visitors and thus revenue for area businesses in a time of need, we also cannot guarantee the ability of those businesses, such as downstream campgrounds, (which are all currently under water), restaurants and hotels to be able to accommodate people. We can tell you with great assurance; we will not put the safety of our members and their families at risk on the basis of “the levee should hold.”

As in years past our policy has been Jamboree registrations are non-refundable. Due to the current circumstances, which we have no control over, all participants who have already signed up for Jamboree 2011 will be given credit for Jamboree 2012. Credit is for Jamboree use only and cannot be transferred to another event or applied towards membership dues.

Thanks again for your continued support throughout the years. Plans are already being made for Jamboree 2012.

Jeff Rheborg, CEO, Varmint Hunters Assn.
