Can outsider beavers save this dried up river?

It's not easy being a river in the desert under the best of circumstances. The ecosystem exists in a very delicate balance, allowing water sources to thrive in the harsh conditions. These water sources in otherwise extremely dry areas are vital to the survival of unique wildlife, agriculture, and even tourism as they provide fresh drinking water for the people who live nearby.

But man-made problems like climate change, over-farming, and pollution have made a tough job even tougher in some areas. Rivers in Utah and Colorado that are part of the Colorado River Basin have been barely surviving the extremely harsh drought season. When the riverbeds get too dry, fish and other aquatic creatures die off and the wildfire risk increases dramatically.

About six years ago, one team of researchers had a fascinating idea to restore the health of some of Utah's most vulnerable rivers: Bring in the beavers.

In 2019, master's student Emma Doden and a team of researchers from Utah State University began a "translocation" project to bring displaced beavers to areas like Utah's Price River, in the hopes of bringing it back to life.

Why beavers? It just makes dam sense! (Sorry.)

Beaver dams restrict the flow of water in some areas of a river, creating ponds and wetlands. In drought-stricken areas, fish and other wildlife can take refuge in the ponds while the rest of the river runs dry, thus riding out the danger until it rains again.

When beavers are present in a watershed, the benefits are unbelievable: Better water quality, healthier fish populations, better nutrient availability, and fewer or less severe wildfires.

It's why beavers have earned the title of "keystone species," or any animal that has a disproportionate impact on the ecosystem around them.

Doden and her team took beavers who were captured or removed from their original homes due to being a "nuisance," interfering with infrastructure, or being in danger, and—after a short period of quarantine—were brought to the Price River.

Despite the research team's best efforts, not all the translocated beavers have survived or stayed put over the years. Some have trouble adapting to their new home and die off or are killed by predators, while others leave of their own accord.

But enough have stayed and built dams since 2019 that the team is starting to see the results of the effort. In fact, beaver projects just like this one have been going on all over the state in recent years.

The water levels in the river are now the healthiest they've been in years. The fish are thriving. Residents of Utah are overjoyed at the results of the experiment.

A column in The Salt Lake Tribune from 2025 (six years after the beaver translocation began) writes that the revitalization of the Price River "helped save our Utah town."

"A tributary of the Colorado River, the Price River runs through downtown Helper. On a warm day, you’re likely to find the river filled with tourists and locals kayaking, tubing and fishing along its shore. A decade ago, it was hard to imagine this scene—and the thriving recreation economy that comes with it—was possible."

Of course, it wasn't JUST the beavers. Other federal water cleanup investments helped remove debris, break down old and malfunctioning dams, and place tighter regulations on agriculture grazing in the area that depleted vital plant life.

But the experts know that the beavers, and their incredible engineering work, are the real MVPs.

In other drying, struggling rivers in the area, researchers are bringing in beavers and even creating manmade beaver dams. They're hoping that the critters will take over the job as the rivers get healthier.

Utah's San Rafael river, which is in bleak condition, is a prime candidate. In on area of the river, a natural flood inspired a host of beavers to return to the area and "riparian habitat along that stretch had increased by 230%, and it had the most diverse flow patterns of anywhere on the river," according to KUER.

It's hard to believe that beavers nearly went extinct during the heyday of the fur trapping industry, and continued to struggle as they were considered nuisances and pests. Now, they're getting the respect they deserve as engineer marvels, and their populations have rebounded due to better PR and conservation programs.

To that I say...it's about dam time!

The oldest whales in the ocean were alive before 'Moby-Dick' and have the harpoons to prove it

These gentle giants have lived through history.

A humpback whale swimming.

You're probably familiar with the literary classic "Moby-Dick." But in case you're not, here's the gist: Moby Dick is the name of a huge albino sperm whale. (Get your mind outta the gutter.) There's this dude named Captain Ahab who really really hates the whale, and he goes absolutely bonkers in his quest to hunt and kill it, and then everything is awful and we all die unsatisfied with our shared sad existence and—oops, spoilers!

OK, technically, the narrator Ishmael survives. So it's actually a happy ending (kind of)!

whales, Moby Dick, poaching endangered species, sperm whale, old drawing, whalers Illustration from an early edition of Moby-Dickvia Wikimedia Commons

Basically, it's a famous book about revenge and obsession that was published back in 1851, and it's really, really long.

It's chock-full of beautiful passages and dense symbolism and deep thematic resonance and all those good things that earned it a top spot in the musty canon of important literature. There's also a lot of mundane descriptions about the whaling trade as well (like, a lot). That's because it came out back when commercial whaling was still a thing we did.

In fact, humans used to hunt more than 50,000 whales each year to use for oil, meat, baleen, and oil. (Yes, I wrote oil twice.) Then, in 1946, the International Whaling Commission stepped in and said "Hey, wait a minute, guys. There's only a few handful of these majestic creatures left in the entire world, so maybe we should try to not kill them anymore?"

And even then, commercial whaling was still legal in some parts of the world until as recently as 1986.

And yet by some miracle, there are whales who were born before "Moby-Dick" was published that are still alive today.

What are the odds of that? Honestly, it's hard to calculate since we can't exactly swim up to a bowhead and say, "Hey, how old are you?" and expect a response. (Also, that's a rude question — jeez.)

Thanks to some thoughtful collaboration between researchers and traditional Inupiat whalers (who are still allowed to hunt for survival), scientists have used amino acids in the eyes of whales and harpoon fragments lodged in their carcasses to determine the age of these enormous animals—and they found at least three bowhead whales who were living prior to 1850. Granted those are bowheads, not sperm whales like the fictional Moby Dick, (and none of them are albino, I think), but still. Pretty amazing, huh?

Bowhead whales reach an average length of 35 to 45 feet, and they are believed to live over 200 years. One of the big reasons for their longevity is that they have genes that may allow for the repair of damaged DNA. Researchers believe that the bowhead is the whale with the longest lifespan. Baleen whales have been found to live longer than toothed cetaceans such as the sperm whale or orca,

This is a particularly remarkable feat considering that the entire species was dwindling near extinction.

Barring these few centenarian leviathans, most of the whales still kickin' it today are between 20 and 70 years old. That's because most whale populations were reduced to 10% or less of their numbers between the 18th and 20th centuries, thanks to a few over-eager hunters (and by a few, I mean all of them).

Today, sperm whales are considered one of the most populous species of massive marine mammals; bowheads, on the other hand, are still in trouble, despite a 20% increase in population since the mid-1980s. Makes those few elderly bowheads that much more impressive, huh?

Unfortunately, just as things are looking up, these wonderful whales are in trouble once again.

We might not need to worry our real-life Captain Ahabs anymore, but our big aquatic buddies are still being threatened by industrialization — namely, from oil drilling in the Arctic and the Great Australian Bight. In the off-chance that companies like Shell and BP manage not to spill millions of gallons of harmful crude oil into the water, the act of drilling alone is likely to maim or kill millions of animals, and the supposedly-safer sonic blasting will blow out their eardrums or worse.

This influx of industrialization also affects their migratory patterns — threatening not only the humans who depend on them, but also the entire marine ecosystem.

And I mean, c'mon — who would want to hurt this adorable face?

Whales might be large and long-living. But they still need our help to survive.

If you want another whale to make it to his two-hundred-and-eleventy-first birthday (which you should because I hear they throw great parties), then sign this petition to protect the waters from Big Oil and other industrial threats.

I guarantee Moby Dick will appreciate it.

Do rattlesnake rattles work like maracas? Nope. They're way cooler than that.

The rattle itself is actually hollow.

How do rattlesnake rattles work?

Ever found yourself face to face with a rattlesnake? Years ago, my husband and I were setting up camp by a lake in Eastern Washington when we saw we had a visitor. Lying in the fire pit was a brown snake that blended right into the dirt. Upon close (but not too close) inspection, we the rattle at the end of its tail. Yikes.

We contacted campground staff, and soon a grizzly older man—face unshaven, hat pulled low, cigarette hanging from his lower lip—arrived at our campsite. He took note of the snake and with zero hesitation, in one fluid motion, he reached into the fire pit, grabbed the snake by the tail, swung it around over his head a few times, and flung it into the forest.

That core memory is the closest I've ever been to a rattlesnake in the wild (and for the record, that's not the recommended method of handling a rattlesnake) but it was close enough. Hearing a rattlesnake rattle is terrifying—venomous as they are—but it's also a relief, because at least they let you know they're there.

I always thought of a rattlesnake rattle like a little tail maraca, assuming it must function in a similar way, but apparently I was wrong. A video on the Odd Animal Specimens YouTube channel shows what you see when you dissect a rattlesnake rattle, and it's wildly fascinating.

- YouTube www.youtube.com

First of all, rattlesnake rattles are hollow. There are no little beads or pellets of any kind rattling around in there. The segments of the rattle themselves are what make the sound, but how they're formed and how they fit together is quite a feat of engineering on Mother Nature's part.

A segment of the rattle is formed by the skin that's left behind at the end of the tail each time a snake sheds. The segments are shaped such that they stay hooked together loosely, but they aren't connected by anything. You can actually pull them apart. The looseness of the segments are what allow them to make sound; when the snake shakes its tail, the segments bump together, creating the rattle.

Rattlesnakes are feared for a reason—they are venomous, and a bite can be deadly if not treated—but they aren't really as dangerous as people might think. Each year, around 5,000 to 8,000 people are bitten by rattlesnakes, and out of those thousands there are only 5 or 6 deaths. According to the National History Museum, that means "you are 6 times more likely to die from a lightning strike or a dog attack, 8 times more likely to die from a TV set or other large furniture falling on you, 14 times more likely to die falling out of a tree, and 95 times more likely to die falling off a ladder" than to die from a rattlesnake bite.

In general, rattlesnakes just want to be left alone and they'd prefer to leave you alone, too. They are not naturally aggressive towards humans. However, if you startle them or provoke them, they may bite.

rattlesnake, rattler, snake attack, snake striking A little rattling sound is one thing. This pose is another. Photo credit: Canva

If you are ever bitten by a rattlesnake, here's what the U.S. Forest Service recommends the following do's and don'ts:

If bitten by a rattlesnake DO NOT:

- Do not make incisions over the bite wound.

- Do not restrict blood flow by applying a tourniquet.

- Do not ice the wound.

- Do not suck the poison out with your mouth.

These methods can very well cause additional harm and most amputations or other serious results of a rattlesnake bite are a result of icing or applying a tourniquet.

DO

- Stay calm

- Call Dispatch via radio or 911

- Wash the bite area gently with soap and water if available

- Remove watches, rings, etc., which may constrict swelling

- Immobilize the affected area

- Keep the bite below the heart if possible

- Transport safely to the nearest medical facility immediately.

Frenetic, high-speed driving places the victim at greater risk of an accident and increased heart rate. If the doctor is more than 30 minutes away, keep the bite below the heart, and then try to get to the medical facility as quickly as possible.

As long as you're not sticking your hands into holes or not paying attention to where you're walking in rattlesnake country, you're not likely to ever need that advice, however. Contrary to popular belief, a rattlesnake rattling doesn't mean it's about to strike. It's just a way for the snake to say, "Uh, excuse me, just wanted to let you know I'm here so you don't do anything stupid, mmmkay? Leave them alone and they'll leave you alone, generally speaking.

"We were robbed": Unexpected rejects from the U.S. National Park System

“If the silver discovery hadn’t happened...Lake Tahoe almost certainly would have been a national park."

Lake Tahoe was almost a national park, but politics got in the way.

You know the adage, “Always a bridesmaid, never a bride.” Well, something similar happens out in the wild: not every natural wonder gets to become a national park. For every Yellowstone or Yosemite national park, there are dozens of equally jaw-dropping American landscapes that were denied this coveted designation—and the unparalleled federal protection that comes with it.

From Lake Tahoe’s radiant blue waters to the fossil-rich canyons of Dinosaur National Monument, there are dozens of breathtaking natural beauties across the country that are just that: natural beauties with thriving ecosystems, but not national parks. Behind each rejection, there’s always a fascinating story of politics, competing financial interests, and a constantly changing definition of what “deserves” national protection waiting in the wings.

Lake Tahoe, national parks, blue water, natural beauty, nature Many people—including Lake Tahoe’s biggest advocate, conservationist John Muir—fought for Lake Tahoe to become a national park.Photo credit: Canva

Often called “the Jewel of the Sierra,” or “Ocean in the sky,” Lake Tahoe is a marvel. Visitors of the 2-million-year-old lake enjoy pristine snow-capped peaks, gorgeous pine trees, and the prettiest, clearest water imaginable. Mark Twain even wrote of Lake Tahoe, “I thought it must surely be the fairest picture the whole earth affords.” Naturally, many people—including Lake Tahoe’s biggest advocate, conservationist John Muir—fought for Lake Tahoe to become a national park, and multiple attempts were made from the 1880s and 1930s.

The problem? Virginia City, Nevada in 1859.

Eighteen hundred and fifty-nine was the year silver was discovered there, and as local historian David Antonucci explains, “If the silver discovery in Virginia City hadn’t happened, the course of history in Lake Tahoe would have been a lot different. It almost certainly would have been a national park."

The resulting mining rush altered Lake Tahoe’s landscape forever, most significantly impacting the tall, ancient trees that dotted the Tahoe Basin, which were systematically chopped down to build mine shafts. Twenty years later, it was estimated that more than 33 million board feet of timber were being cut down annually. To put that into perspective, that’s the equivalent of 2,749,999 cubic feet: the amount of wood required to fill 1,150 shipping containers or 88,000 Olympic-sized pools.

Due to this massive degradation of Lake Tahoe’s precious resources, the National Park Service later concluded that the extensive tourism and land development had compromised the lake’s nature beyond repair, ruling it unsuitable for national park designation.

Why do places seek national park status in the first place? Lake Tahoe has no ego; the land itself does not seek fame, fortune, or glory. But there are several incentives both for the land and the surround communities that make the fight for national park status worth it. National parks enjoy certain VIP privileges, including an army of park rangers and maintenance crews provided by the federal government.

National parks, like the scenic Great Smoky Mountains National Park, Grand Canyon National Park, and Zion National Park, are protected to the highest degree possible against resource extraction, land development and other harmful practices. The are nothing short of astounding: miraculous havens for animals and native plants, flourishing wildlife habitats, and the preservation of vital cultural resources.

Then, there’s the tourism aspect: another powerful motivation for communities to support national park designation is the incredible bump in sightseers—paying visitors—that begin to arrive. National parks are tourist magnets, with Great Smoky Mountain National Park welcoming more than 12 million visitors in 2020. It’s the type of tourism that can turn a rural town into a bucket list destination and economically alter a community forever. Think of the last national park you visited and the crop of tourism-related businesses that surrounded it: lodging, restaurants, themed retail stores, guided tours, and more.

Sadly, Dinosaur National Monument is another destination that never enjoyed national park status and the plethora of perks that come with it. Nestled in the rugged borderlands straddling Colorado and Utah, this huge national treasure spans over 210,000 acres—that’s larger than Bryce Canyon and Zion National Park combined. The natural wonder features an unparalleled 800 paleontology sites and the Carnegie Quarry, which boasts a 150-million-year-old wall full of roughly 1,500 exposed fossilized dinosaur bones.

Dinosaur National Monument also offers astonishing views of the nighttime sky, deeming it an International Dark Sky Park (IDSP) in honor of its exceptional nocturnal environment and supreme views of the cosmos. Obviously, this archaeological beauty would be a shoo-in for national park status, right?

Unfortunately, meddling outside forces struck again: after multiple attempts, Dinosaur National Monument has not been formally rejected as a national park, but it's progress has been stalled for a long time due to local opposition. Commissioners and stakeholders in the area feared that a national park designation would jeopardize their various ranching and energy investments and blocked any attempts to elevate Dinosaur National Monument to national park status.

Becoming a national park is no walk in the park. Rules are scrupulous, community support is vital, and the power of public perception matters. In many ways, that’s a good thing: the National Park Service’s uncompromising criterion ensures precious American tax-payer money is reserved for only the most exemplary resources in the country, both natural and cultural, in a world that, increasingly, seeks to destroy them. But what of Lake Tahoe, Dinosaur National Park, Silver Falls in Oregon, or the Adirondack Mountains?

For reasons that have nothing to do with their importance, significance, or natural beauty, these landscapes lack national park designation and the protections that come with it. But that doesn’t mean they’re not worth visiting. So, the next time you’re planning a nature trip, consider adding these beauties to your list. You just might be pleasantly surprised.
