I’m caught in an epic electrical storm in a deep gorge in Montana’s Bear Tooth range. Lightning flashes instantly deliver ground-shaking thunderclaps crashing and booming off thousand foot granite walls. A battleground of the wildest kind! Plunging waterfalls absorb sound energy mimicking an avalanche of boulders. I’m immersed in electrical aura!!
Two days later, I discover a friend was caught in a storm of similar magnitude while exploring high country in the Bear River Range of Northern Utah. He too felt nature’s omnipotence, describing it as heavy battlefield artillery.

I find our earth’s atmosphere to be mystical- from rainbows to mystery clouds- from tornados to hurricanes and tennis ball sized hail.

The earth’s onionskin-thin atmosphere is a rich soup from microscopic life and dust particles to avifauna and airplanes. Uniform to the eye, its mixture is anything but. Examine a column of air most anywhere and you’ll find it different from any other air column. The components found in this heterogeneous mixture are of endless variety as any atmospheric chemist will tell you.
Many aerosol substances of natural origin are present in locally and seasonally variable amounts, including dust of mineral and organic composition, pollen and spores, sea spray, and volcanic ash to name a few. Various industrial pollutants also may be present as gases or aerosols, such as chlorine and fluorine compounds and elemental mercury vapor. Sulfur compounds such as hydrogen sulfide, sulfur dioxide, and oxides of nitrogen may be derived from natural sources or from industrial air pollutants.

Clouds are utterly fascinating for their beauty and how they are formed. Why do they suddenly appear from thin air? Clouds have three essential ingredients- small particles, water vapor, and a critical temperature called dew point. Considering the air is anything but uniform- including temperature, humidity, and particle types, when these three ingredients converge, Newalla- a cloud is birthed!

My favorites are cumulonimbus- also called thunderheads. They can reach heights of 6 miles and may spawn violent storms, including tornados. They are saturated with both electrical and mechanical energy. Due to updrafts causing friction among icy particles, the cloud becomes electrically charged with positives on top and negatives on the bottom. The strong negative charge at the clouds base creates a temporary positive charge on the ground. Considering opposite charges attract, an exchange of electrical energy may occur- lightening! The extreme heat, averaging 36,300 degrees F, causes molecular collision manifested as sound energy. It can be deafening, resulting in temporary or permanent hearing loss.

Our mountains are great cloud makers, referred to as orographic lifting. As the air rises to travel over the summit, it expands and cools, reaching the critical dew point mentioned. Thus, as one increases a thousand feet in elevation the temperature drops about 4 degrees F and gains about 4” of annual precipitation.
More reason to marvel at our miracle planet, more reason to celebrate its beauty, mystery, and fragility.

Natural Quiet and Darkness in our National Parks

If visitors find locations in Utah’s National Parks, where very little man-made sounds are heard, it can be a breathtaking experience. A park visitor may canoe along riparian habitat and hear a variety of bird calls, or hike a trail and come around a bend to see a few deer jump over the sage-brush.

These types of experiences may also occur after dark when visitors participate in stargazing or a full-moon hikes.

Mark and Sallie Shelton said, “Utah dark skies are our passion! The [dark] sky and quiet solitude are magical. Visitors, from around the world, are in awe when they get their first [heavenly] glimpse of [the Milky Way] and see the stars shining like diamonds on dark velvet.”

Protecting the quiet and darkness of our National Parks has become a priority for many managers and researchers.

Christopher Monz, professor in the Department of Environment and Society in the Quinney College of Natural Resource at USU joined with five other scientists who have all worked on issues of noise pollution and light pollution to compile the book, “Natural Quiet and Natural Darkness: The “New” Resources of the National Park.”

Monz explains, “[We wanted] to compile, in one place, the best science on both the social and ecological dimensions regarding the importance of the resources of darkness and quiet, and the consequences of them slowly disappearing in our most precious protected areas – the national parks.”

The book gathered many interesting findings.

One is the concept of “listening area” which is the distance an individual (human or animal) can hear normal sounds and calls that they’re evolved and adapted to. For a bird species it might be a mating call, for deer it might an alert response from a predator.

As noise increases the listening area may decrease dramatically.

Monz said, “In the United States noise from roads has increased three fold since 1970.”

A three decibel increase in noise results in a 50 percent decrease in listening area. If there is a 10 decibel increase, the result is a staggering 90 percent decrease in listening area.

Monz explains, “If you put noise into the environment there is the potential for significant ecological implications, particularly for wildlife. They can no longer be reliant on the sense of hearing to carry out normal activities…some species will move out of those noisy areas to quieter environments which creates a displacement effect.”

For humans, this means we have less opportunities to engage with the sights and sounds of nature.

One success story outlined in the book occurred in Muir Woods National Monument in California. Monz said, “Simply by putting up signs which raised the visitor’s awareness of the environment they were in, and the importance of quiet for other visitors, the noise decreased by 2 decibels. This gave folks an opportunity to experience better natural quiet environment and a little bit more biodiversity from the standpoint of hearing bird calls from the surrounding forest.”

The book also provides ideas for managing the resource of darkness in the National parks.

Monz said, “Right now 80% of the world’s population lives in locations where there is some compromise of natural darkness…most will never see the Milky Way.”

Cedar Breaks National Monument, which has the highest star gazing site at 10,500 feet, received an award from The International-Dark Sky Association (IDA) for preserving its Dark skies.

The authors of “Natural Quiet and Natural Darkness” hope the book will get in the right hands to provide park managers with this easily accessible tool where they can find the best science and actionable ideas to increase quiet and darkness in our National Parks.

In the Eyes of a Bear

We call him Old Ephraim up here in Cache Valley. He's a tale known by just about everyone: one of the last brown bears in Utah, shot and killed by Frank Clark, in August, 1923. The account that's usually told spins the bear as both highly intelligent and dastardly, almost even sub-animal, of a creature who is the last because he is the most conniving and monstrous. His death came at the hands of a shepherd who had tracked the bear for nearly a decade, taking over 40 others in his pursuit, only to finally overcome the giant with luck and a repeating rifle. In Old Ephraim's death, he was skinned, burned, and buried. His hide was eaten by moths in the slope of Clark's barn. Today, his skull resides in an exhibit at Utah State University, and his bones have been long poached by treasure hunters. His grave holds no bear but that which we imagine.

What I take away from this story, though, is not what others have typically taken away when I read the accounts. For those long-past authors, it has always been of the glorification of Clark’s struggle; for overcoming the agent of a primeval, and thus incompatible, nature; for the noble easing of future fears by finally taking that monster bear. For me, I take away how Clark, years later, bravely chose to regret his choices, which at the time of their making were too far already decided by habit rather than concise intent. Clark stated about it, “Was I happy? No, and if I had to do it over, I wouldn’t kill him… I could see the suffering in his eyes…” That suffering had been passed on to him, it seems.

Blame for the end of Utah’s last great bear, though, cannot be placed upon the man, nor the firearm, nor the bear. Blame can only be attached to what bonded them as kin: that both man and bear had been dealt their hands by their being, and they played them the only way they had been shown, descendant of a long line of teachers whose most underlying motivation was honest survival. This is what connected the two in the moment of their struggle. They were united by fate because of what made them similar, not different.

In his telling of his regret, Clark dared who he was, with who he strove to be, even in his later life. He was, after all, a self-professed lover of nature, and held holy the wild places where he spent dozens of summers. His regret was not a fault, but a truss of strength which honored this deeper value. He understood that, if you allow it, nature will take you to the great questions through flowers and birds and a strenuous life, if even for a small while, and even after you have erred. Nature is a hopeful place; an accepting place. Out there, “its” become “thous”, and the ego and all its fleeting impulsivities are surrendered to the ultimate authority of deep experiences within the land.

Hemingway said that, “The world breaks everyone and afterward many are strong at the broken places.” In this reflection, Clark’s story is not only about the fall of a great creature, nor a man who struggled to bring him down, but about how a man painfully earned the bravery and strength to see what he thought set him above, become reflected equal from him, in the knowing eyes of the last great Utah bear.

American White Pelicans

I first caught sight of the eight pelicans swimming in s straight line towards the waters edge, looking a lot like a tank division in in an old WWII movie I slammed on the brakes just in time to see them all dip their bills into the water, come up spilling water and cock their heads back And then, gulp! Fish slid down their throats.

Wow, I thought. These pelicans are working together to to drive the fish into the shallow water’s edge where they can easily scoop the up And then it got better. Fanning out, the pelicans regrouped in a circle Swimming towards the center, they tightened the noose. And bam! Dip, scoop, knock back some more fish

I was amazed at how soundless and seamless it all was and could have watched for hours, but I was on the one lane auto route at the Bear River Migratory Bird Refuge and the cars behind me were starting to honk their horns, so I reluctantly moved on.

As soon as I got home I plunged into research on this majestic bird, beginning with the bill. When the pelican dips its bill into the water, the lower portion expands into a flexible sac that allows the bird to to scoop up as much as 3 gallons of fish and water. When the pelican cocks back its head, the sac contracts, the water is expelled through a barely open bill, and the fish swallowed. The huge pelican bill, which at first glance looks like a formidable weapon, is actually an exquisitively designed fishing net.

Archeologists have found pelican skulls dating back 30 million years, so this unique bill has definitely passed the test of time.

Back at the refuge I was able to turn into a visitor pull out and pick up the rather stunning bit of information: these pelicans fly in from Gunnison Island in the Great Salt Lake, over the Promontory Mountains, daily to forage for fish. That’s a 30 mile trip each way!

Long before the Mormon pioneers arrived in Utah, pelicans were building their nest on Gunnison Island. They were briefly disturbed when an artist, Albert Lambourne, tried to homestead for a year in 1850, and a guano mining company dropped off a crew – a Pole, a Russian, a Scot and an Englishman- to mine the bird poop. But the operation wasn’t profitable, and when it closed down, the pelicans reclaimed the island. Each March the birds fly in from as far away as Mexico, build their nests, and raise their chicks. The rookery is the largest in the US. In 2017 the pop was estimated to be as high as 20,000.

Back in Cache Valley in 2010, Jordan Falslev built a viewing platform near Benson Marina, The Pelican Perch, as his Eagle scout project. There used to be hundreds of pelicans out there on the water, but when I stopped by last week I didn’t see a single one. Numbers are way down now largely because the dropping water level in the Great Salt Lake have exposed a land bridge to Gunnison Island that allows predators to ravage the nesting site.

You can still catch sight of a pelican in flight in Cache Valley. (Their wingspan is 10 ft. Rudy Gobert, in comparison, has a wingspan of 7 ft 9 in.) But for my money, the best show in town is watching packs of pelicans hunt for fish at the Bear River Migratory Bird refuge.
