Cache Valley Utah and the Bear River range that border its eastern edge are anomalies. Especially considering the abundance of water coursing through its canyons and valley bottom. Following a prolonged drought in the Salt Lake Valley in the 1850’s, it was the abundant wetland plants in cache valley’s center that first enticed Mormon pioneers to settle here. Fed by numerous streams discharging from the Bear River range and the mighty Bear River, these waters were trapped by the fine sediments of Lake Bonneville. The result was lush green forage, even in dry years. The native tribes and mountain men knew it well, and followed the wildlife which flourished here long before the arrival of pioneers.

I’ve quenched my thirst from the countless springs found in our eastern canyons and basins, always a reminder of our good fortune. One might ask, what set of circumstances allow Cache Valley to be so well watered? What follows are my hypotheses. A combination of geology, and climate.

The Bear River range, a subset of the Wasatch, is close to 20 miles wide, and averages well over 8,000 feet in elevation, topping just shy of 10,000 feet at Naomi Peak. Its height and width allow it to capture an abundant snowpack in normal years. The regional climate may be partially responsible as well. Extreme cold temperatures compared to surrounding mountains, the second coldest measured in the 48 states, atop Logan Canyon, enhance precipitation.

Geologically this mountain range is composed primarily of limestone and dolostone, both are excellent formations for absorbing water, which reappears as springs forming the headwaters of its numerous streams. As snow melts, water seeps through the broken limestone, referred to as Karst topography, until it hits an impervious layer of shale or mudstone, where it collects and eventually punches through a fractured seam of rock, to surface as a spring.

All are tributaries of the Bear River, plummeting from the north slope of the Uintah’s, a unique river system with its headwaters and mouth close to the same latitude. It provides nearly 2/3rds of the service water flowing into the Great Salt Lake. This is the longest river in North America which doesn’t end up in an ocean. With a changing climate proposed, further impoundment and diversions of these waters, the future of our unique hydrology is under constant threat. I wish us great wisdom in how we chose to manage this vital resource.

Living in snake country – six things to consider

Summer is here. People will be using the great outdoors more often, and that includes the many tourists who have discovered Utah’s beauty and diversity. Caution is always needed when traveling in wild country, and today I refer to an article titled “Living in Snake Country-Six Things to Consider” written by Terry Messmer, Utah State University Extension wildlife specialist.

Ask an Expert: Living in snake country – six things to consider
Written by Terry Messmer, Utah State University Extension wildlife specialist

For many, the sight of a snake is what nightmares are made of. Unfortunately, all too often Hollywood has taken advantage of people’s fear of snakes for profit. Some companies may also market products or services that are ineffective at repelling snakes, and in some cases, these products may actually increase the risk to people and pets.

The U.S. Centers for Disease Control estimates that 6,000 to 8,000 people are bitten by venomous snake annually and that up to six snake bite victims may die. Annually, an estimated 90 human deaths occur from various venomous animal encounters. The stings and subsequent anaphylaxis from bees, wasps and hornets are responsible for over 90% of the reported human deaths.

Of the 31 species of snakes found in Utah, seven are venomous. These are commonly called pit vipers because of the pit located between their nostrils and eyes. Most pit vipers found in Utah also have tails with a series of rattles, hence the name rattlesnake.

All snakes are classified as non-game animals and are protected by Utah state law. A person cannot lawfully collect or possess a live wild snake without receiving a Certificate of Registration from the Utah Division of Wildlife Resources. When there are human, domestic pet and livestock safety concerns, a venomous snake may be killed without a certificate.

Because most snakes in Utah are non-venomous, most human-snake encounters are generally not dangerous. However, if you encounter a venomous snake and are bitten, the consequences could be serious. Consider these tips.

If you encounter a snake, your best strategy is to leave it alone. Every year, hundreds of want-to-be herpetologists and snake charmers are bitten when they try to capture or kill a snake. Even dead snakes have been known to bite by reflex action. More than half of the reported snake bites were a result of someone trying to handle or kill the snake. It is always best to leave the area if you encounter one.

When rattlesnakes are encountered or disturbed, the rapid vibration of their tails will make a characteristic rattling sound to warn the intruder of their presence. However, not all rattlesnakes will “rattle” when disturbed. For this reason, when you are in rattlesnake country, you must pay close attention to where you walk, sit and place your hands. Rattlesnakes can be found throughout Utah in sagebrush, pinon-juniper woodlands, sand dunes, rocky hillsides, grasslands and mountain forests.

If you hear a rattlesnake “rattle,” stand still until you can locate where the sound is coming from. Do not try to jump or run. If you do, you may end up within the snake’s striking range.

If bitten by a venomous snake, do not engage in physical activity such as walking or running. Do not apply a tourniquet to the area above the wound and do not apply a cold compress to the bite area. Do not cut into the bite. Do not take anything by mouth, including stimulants or pain medications, unless instructed by a physician. Do not raise the bite area above the level of the heart, and do not try to suction the venom, as doing so may cause more harm than good.

All venomous snakebites should be considered life threatening. When someone has been bitten by a venomous snake, time is of the essence. If possible, call ahead to the emergency room so anti-venom can be ready when the victim arrives. Until then, keep the victim calm, restrict movement and keep the affected area below heart level to reduce the flow of venom. Wash the bite area with soap and water. Remove any rings or constricting items, as the affected area will swell. Cover the bite with clean, moist dressing to reduce swelling and discomfort. Monitor the victim’s vital signs (pulse, temperature, breathing, blood pressure). If there are signs of shock, lay the victim flat and cover with a warm blanket. Get medical help immediately. If possible, bring in the dead snake for identification if this can be done without risk of injury.

Bites from venomous snakes will almost instantly show signs of swelling and discoloration of the surrounding tissue. Other symptoms include a tingling sensation, nausea, rapid pulse, loss of muscle coordination and weakness. Also, bites from rattlesnakes will show two characteristic fang marks (punctures) as well as other teeth marks. Non-venomous snakebites are harmless, but there is still a risk of infection. If bitten, clean and sterilize the wound much like you would a cut or abrasion.

Silence

Silence is a rare commodity in the world we have created. Our senses are bombarded with all descriptions of sound to the point of sensory exhaustion. Likened to PTSD when violating a safe threshold, it may be time to find an escape.

Our avian friends are experiencing the same affliction.

As I was reminded on my early am canyon run, birds rely heavily on vocalizations to communicate. Lazuli buntings, warbling vireos, the barely audible blue gray gnatcatchers added pleasure to my uphill slog. But not singing for me, rather to attract mates, defend their territory from rivals, and warnings for predators.

The excess racket that humans contribute prompt some species to sing at different times and in different ways. In Mexico, researchers found that house finches raised the pitch of their lowest song notes in response to road noise, and also held them longer. A study published in Current Biology examined song changes of the great tit across ten European cities revealed that in each location the birds omitted the low-frequency portion of their call.

However helpful such biological tricks may be for some birds, the nearer one gets to a densely populated town or city, the less diverse the avian community becomes. Not all species have the ability to work around the commotion.

House sparrows, which have a significant low-frequency component to their songs, have suffered population declines of two thirds in Great Britain over the past few decades. A university of Colorado at Boulder study found that mourning doves and black-headed grosbeaks avoid nesting near sites where natural gas is being extracted, as they cannot tolerate the noisy compressors. Blood tests revealed that levels of corticosterone in birds closest to the gas compressors were far lower than normal. This initially came as a surprise to the researchers, because corticosterone is the bird equivalent of cortisol — the hormone that prompts the human body to release a flood of adrenaline, increasing blood pressure, and jolting our brain with sugar. Only 21 different species resided in the noisy sites, compared to 32 in the quiet ones.

Many of us have grown accustomed to the hustle and bustle of the 21st Century, perhaps to our demise, but the birds may have a lesson to teach us about the value of peace and quiet: just how frighteningly little of it remains. According to an audio ecologist study, fewer than five minutes go by before the average patch of wilderness is interrupted by the sounds of human interference.

After years of recording the natural environment in places all around the globe, Gordon estimates that fewer than a dozen truly silent places are left. It is not just the birds that are vulnerable, either. The breeding success of some Australian frog species is being impacted by traffic noise, and ocean noise pollution caused by boat engines. Who knows what variety of species may be affected? Noise might seem an unlikely player on the ecological stage, but further study is definitely warranted on impacts of the anthropogenic racket.

The Bear River’s History and Contributions

The Bear River meanders almost 500 miles from its headwaters in Utah’s Uinta Mountains to its mouth at the Great Salt Lake, making it the longest river in North America which does not empty into an ocean. Instead, the Bear River serves as the main source of fresh water for the Great Salt Lake, a vast terminal lake in the Great Basin with no outlet except evaporation. This hasn’t always been the case, though. The Bear River once flowed north, serving as a tributary of the Snake River, and ultimately reached the Pacific Ocean via the Columbia River. That is until about 140,000 years ago when the earth erupted in present-day southeast Idaho and spilled lava across the Bear River’s path.

Now obstructed by expansive lava fields hardening into immense walls of basalt rock, the Bear dog-legged to the south and became—for the first time—a source of fresh water for the ancient inland sea that would eventually become the Great Salt Lake. The river was tenacious, though, and spent its time not only feeding fresh water to ancestors of the Great Salt Lake but also chiseling away at the basalt columns that obstructed its way toward the sea. The river was finally rewarded for its efforts millennia after having been cut off from the Snake and Columbia River Basins, and once again became a tributary of the Snake River. This fate would not last, however. Roughly 35,000 years ago, violent geology would have its way again. More lava flows around present-day Soda Springs, Idaho, bent the Bear River back toward the Great Basin where it still empties today.

And this has been a boon for the millions of residents—Homo sapiens and otherwise—of the Wasatch Front here in Utah. Let’s consider for a moment what life in central and northern Utah would be like if not for the Bear River. For starters, the Great Salt Lake would lose 60% of its annual inflow, drastically reducing its volume. I wonder if Brigham Young and his Saints would have even considered settling in the Salt Lake Valley after enduring the many lake-bed-dust storms courtesy of the Great Salt Lake that are becoming a growing concern today. We would certainly be deprived of the world-class migratory bird and wetland habitat supported by the Bear River at the famous Bear River Migratory Bird Refuge. Last fall, Ogden’s Standard Examiner newspaper reported that, quote, “the river had disappeared into a vast mudflat that used to be Bear River Bay.” Experts cited irrigation, municipal, and habitat uses in addition to a host of environmental and climate factors as causes of the Bear River becoming “tapped out” before it reached the Great Salt Lake. A snowpack that has doubled last year’s total according to the Salt Lake Tribune has the Bear River Basin’s snowpack brimming at nearly 300% its average this time of year. This promises to turn things around for the Bear River and the many species which depend upon it.

A complex and interdependent collection of variables impact the Bear River and its hydrologic fate—not least of which are humans, ecology, climate, and the occasional volcanic eruption.
