I Love Snow

I love snow! It began when I was old enough to know the difference, and has continued since. We kids always celebrated the first snow of the year at our home in northern Wisconsin. We waded through it, ate it, made snow angels, looked for the most beautiful snowflake, dug snow caves, and waited for a warm up so we could make snowballs, snow people, and snow forts. Once it got deep enough, we broke out the 6-person toboggan and trudged up the biggest hill we could find. And we couldn’t imagine a Christmas without snow!

When we moved to Cache Valley Utah 34 years ago, I was delighted to learn of its superb snow, reminiscent of N. Wisconsin. Further, I learned of its life and death importance for wildlife. Too much, or too little could spell doom for many of our critters. In a heavy snow year, our deer fawn crop may take a major hit- up to 80% mortality, while small mammals can thrive. Snow is an excellent insulator when deep enough- 8 inches or so will maintain a subnivean (beneath the snow) temperature of 32 degrees when the ambient temperatures plunge well below zero above. Further, they are better protected from predators. Too little snow tells a reverse story- great for predators, but disastrous for their prey.

Snow isn’t just snow. According to those who live in the high latitudes- Eskimos, Siberians, and Scandinavians, they have between 180 and 300 words for different types of snow. As a skier, I have a few myself- powder, crusty, gropple, corn snow, and slush. I’m sure you can guess which of these I prefer.

Utah is world renowned for its extraordinary, low moisture powder- less than 8% water. You’re basically skiing on air. I’m aware of only one other location that beats us- Japan’s Hokkaido mountains with only 4% water content.
Another element of snowfall for the Wasatch front results from the very large lake to our west. Thanks to the Great Salt Lake, our snowfall gets a considerable boost from latent heat and added moisture from this great lake. Additionally, airborne salt particles enhance the formation of snow producing clouds.

I must share an extremely strange and rare phenomenon referred to as “thundersnow”. While skiing the North Ogden bench many years ago, an approaching ominous cloud delivered lightning and thunder, shaking the ground enough to bring up swarms of worms to the snow surface. It took a double take to realize what I was witnessing!
Another strange snow phenomenon is an avalanche. This once soft, pliable medium instantly transformed to cement as the avalanche settles. The friction of sliding snow removes the snowflake crystalline structure, changing it from fluff to a high-density medium. The friction generated heat melts it enough to form the deadly tomb that has encased many.

As the Great Salt Lake shrinks from stream diversions and a warming climate, combined with a dwindling winter season, I cannot help but wonder what will become of our indispensable mountain snowpack, essential for Utah’s water supply and our winter recreation.

Insect Musicians

It gives me great pleasure to take a moonlight walk on these warm summer nights, serenaded by a gazillion insect musicians. Pulsing in unison with a background of cricket chirps, it reminds me that summer is waning and I must enjoy what remains!

As birds grow silent with nesting season past, I become aware of the gradually intensifying chorus of the inset tribe- a cacophonous mixture of chirps, trills, ticks, scrapes, shuffles, and buzzes. What a joy to behold these choruses of males, serenading females of their own species until cold weather dampens the chorus and heavy frost finally brings it to a close. Crickets, katydids, grasshoppers, and cicadas are prominent songsters. They can be found in trees, shrubs, lawns, fields, woodlands—nearly all habitats, and sometimes inside our homes.

My USU entomologist friend recommends the Snowy Tree Cricket as a champion night chorister here among the insects. It’s “snowy” name is derived from its pale coloration causing it to appear white. Snowy Tree Crickets sing from brushy understory plants at forested margins or within open woodlands. During cold spells, they can be found close to the ground on the trunks of small trees where they find a warmer micro-climate. It is also referred to as the “thermometer cricket” due to its accuracy of giving the temperature in degrees F. Just count the chirps for 15 seconds and add 40.

The Spring and Fall Field Crickets are next in line as musicians. They look very similar to each other, but are two different species. The season they appear helps identify them. Another difference is their life histories. Fall Field Crickets overwinter as eggs while the Spring version as nymphs.

Spring Field Crickets develop quickly when warm weather arrives and adults typically appear and begin singing and mating in late spring, continuing until late June or early July when they finish laying eggs and die off. In contrast, Fall Field Crickets hatch in the spring, and adults don’t appear and begin singing until mid to late July, after which they continue singing and mating into the autumn, when they are finally killed by frosts. In most areas of overlap, there is a period of silence in midsummer when neither species is heard.

Finding and identifying a singing insect can be a fun challenge. With the help of a flashlight and considerable patience, you will be able to track down individual singers, and perhaps even view a singing performance firsthand! Many are small and well camouflaged in their green and brown coats, and they sit motionless when singing, blending into their surroundings. Many sing only in the dark of night. Use LED lights as their spectrum seems to enhance finding them.

Weather Wonders

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.

Sego Lily

With Pioneer Day’s a few weeks away, it’s time to honor a very special plant that saved many Utah pioneers.

It’s been a banner year for our state flower. The sego lily has graced our meadows since early June, now in its late stages at lower elevations. It has generated many stories in our state. Before I launch them, I must compliment it’s delicate beauty and love for adverse conditions- the dry, rocky soils in which it’s found. The sego lily personifies the tough, resilient, beautiful pioneer spirit.

Brigham Young declared the sego lily “a heaven sent source of food.” Friendly Native Americans taught Mormon settlers how to harvest and prepare the bulbs for much needed survival food when a devastating cricket infestation destroyed crops.

From pioneer journals:

“”In the spring of 1848, our food was gone. Along the month of April we noticed all the foothills were one glorious flower garden. The snow had gone, the ground was warm. We dug thousands of sego roots, for we heard that the Indians had lived on them for weeks and months. We relished them and carried them home in bucketful’s. How the children feasted on them, particularly when they were dried, for they tasted like butternuts.”
Elizabeth Huffaker, Salt Lake City

And here is another one:
“In my childhood our whole group of children used to go east of town, each carrying a sego digger. It was a piece of wood sharpened on one end, and flat on the other. We would just go out of town and look for segos, which were plentiful. When we found them we each went to digging by putting the sharp end of the stick into the ground close beside the sego, and pressing down on the flat end of the digger until it was a few inches in the ground. Sometimes we pounded on the top of the digger with a rock…when the stick was far enough into the ground to suit us, we just pushed it to one side and up came the segos. Then we ate them, and oh how we enjoyed hunting them.”
Lorena Washburn Larsen, 1868, Manti, UT

Native Americans considered the sego lily a sacred plant and developed culinary uses for its bulbs, seeds, and flowers. Many tribes created a healthful porridge from roasted or boiled sego lily bulbs. Several tribes considered it sacred. For the Navajo it was one of the “Life Plants” used for ceremonial purposes. Sego was derived from the Indian word Sego. Many Indian women were named Sego or Sego-go-chee. The Spanish named it mariposa, their word for butterfly for these beautiful mountainside flowers looked like butterflies.

The sego lily was formally designated as the Utah State Flower in 1911 chosen for its natural beauty as well as its historical significance.

The lily gets its scientific name Calochortus Nuttalli, from Thomas Nuttall, a naturalist, who collected the sego lily in 1811 while traveling along the Missouri River. It’s found throughout the western states. Please do not disturb this iconic beauty. Photos are encouraged!
