Back in October 2019, the ranger at the Great Salt Lake State Park began to notice a white mound forming on the sand flats behind the visitor center. The white mounds turned out to be hydrated sodium sulfate – known as mirabilite- which was being carried to the surface by the upwelling of a fresh water spring. Since the 1940’s geologists have known that in this area, 30 inches below the surface, there was a 3 – 6 foot thick shelf of mirabilite. They knew about the fresh water springs What was new was cold air. Since this stretch of sand was no longer underwater, the mirabilite carried to the surface stayed there as crystals, piling up on each other, puddling and spreading out. One mound rose to the height of 3 feet.

When the mounds started to form again this winter, I jumped at the chance to to go and take a look. I must admit at first I was a little underwhelmed at the size, perhaps because the Kennecott Smelter Stack nearby dominates the view, rising to 1,215 feet – roughly the same height as the Empire State Building. But the park ranger got my attention when she told us that mirabilite mounds have only been seen in four places in the entire world – the Canadian Arctic, Antarctica, Central Spain, – and Utah. Just seeing them turns out to be a rare winter treat. When the air warms to 50 degrees, the mirabilite will crumble into a fine white powder and disappear.

My mind flashed back to a trip I’d made to the other end of the lake ten years ago. I’d just graduated from the docent training class at the Utah Museum of Fine Art, and a friend and I wanted to celebrate by having High Tea at the center of the Spiral Jetty, a 1,500 foot, long, 15 foot wide coil of black basalt rock – a stunning example of land art jutting out from the northern shore. We’d been warned that it might be underwater, but when we arrived we were delighted to find we could easily walk to the very center of the spiral as the lake water gently lapped at the edges of our shoes. We clinked our tea cups, and toasted the greatness of the lake.

Suddenly I wanted to see the jetty again, so I hopped in my car and drove to the remote site. I saw the Spiral Jetty was now high and dry. Drifting sand had already started to bury parts of it. The water’s edge was now over 300 yards away. I thought of the millions of migratory birds that would be arriving in the spring to rest and feast on the tiny treasures of the lake, the brine shrimp. I hoped a smaller lake would still be enough for all of them.

The recent words of the director of Friends of the Great Salt Lake, Lynn de Freitas, rang in my head: “The Great Salt Lake is a gift that keeps on giving. Just add water.”

Sled Dogs-Sheer Joy

As the snow continued to pile up this winter, I started to ask around about sled dogs.

I soon bumped into a friend who had a friend in Preston who trained and occasionally raced his team of 14 Alaskan Huskies.

This musher graciously offered to give me a ride on one of his training runs. I showed up all smiles as he was harnessing his team. The dogs were excited to go and actually howling with happiness. The musher asked if I wanted to get in – or ride up the trail a bit on a snowmobile with his teenage son to a more level spot. In a rare moment of sanity, I opted for the snowmobile.

The machine had just pulled out of the yard when I heard his son say, “Oh, No!”

I looked back in time to see the sled tip over, sending the musher sliding across the driveway and under my car parked at the end of it. I jumped off the snowmobile as the dogs shot past us with the empty sled. The dogs were gaining on a truck up ahead, then shot past it with the snowmobile in hot pursuit.

I was left standing in a snowbank wondering if I’d wandered into a James Bond movie.

My first encounter with sled dogs had gone a lot smoother. I was visiting Denali National Park in Alaska and the rangers were introducing us to one of the dog teams that they still use to patrol the park.

But the most famous sled dogs are the freight teams that carried anti-toxin from Anchorage to Nome during an outbreak of Diphtheria in 1925. The dog teams ran a thousand miles and are credited with saving hundreds of lives.

For the last 50 years, modern mushers have retraced this journey in the ultimate sled dog race, the Ididarod. The best account I’ve read about the world of training sled dogs and running the Ididarod is Gary Paulsen’s book Winterdance. Just before going on a training ride, he discovered, “the gangline was trembling, quivering like a string on a guitar. It fairly hummed and I felt there was great power there. The trees in the yard went by in a mad blur and we left the yard at warp speed.”

Paulsen also lets us in on the deep relationship mushers form with their dogs: “As they understand you will give them meat when they run, and love when they run, and your soul when they run – as they learn to feel that, understand that, know that – they are no longer sled dogs – they become distance dogs, dogs that cannot, will not be stopped.” Paulson ran the Iditarod in 1983. It was a wild ride that took 17 days. But he finished.

Meanwhile, back in Preston, our teenage hero had caught up with the runaway team, made a flying leap from the snowmobile onto the empty sled, and somehow managed to stop the team. Pretty soon the musher and I caught up.

“Do you still want to get in?” he asked.

“Sure,” I said.

And we were off. The dogs settled into a steady trot. From then on it was all Sun and Snow and the sheer Joy of sliding quietly through the magnificent winter scenery.

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.

Sliding on Ice can be Fun

When cold weather sets into Cache Valley, I usually begin to grumble. But this year, when the weather warmed up and the snow turned to rain, my grumbling got a lot louder.

Everywhere I looked, the sidewalks and roads were covered in ice. I announced that falling on ice was my least favorite activity. I hated ice.

Then I got an unusual Christmas letter from an old family friend, Paulette Campbell. This letter told the story about the skating pond her 3 sons had built for 15 years at their Logan home. The yard was 30 ft wide, 60 ft long, and flat as a pancake – perfect for creating an ice rink. But it took a lot of work. The boys would begin by packing the snow with a heavy roller pulled by their garden tractor. Then they got out the garden hose and sprayed the surface. Three hours later the water had frozen and it was time to spray again. For the next five nights the family pitched in and the ice got sprayed every three hours. The boys packed down the lumpy spots with a shovel.

When the pond was ready, the neighborhood kids flocked to the pond to skate after school. But at 8pm, the floodlights came on and the big kids took over the ice. It was time to play hockey. The boys’ grandparents, who lived next door, pulled their chairs up to the bay window and watched. They insisted on paying the water bill. They insisted the entertainment was worth it.

By the time I finished reading the letter, I had to admit sliding on the ice could be fun.

I was also starting to rerun in my mind my own family ice story. My cousin, Jill Bakken, had been recruited out of high school by the US Olympic committee to give bobsledding a try. Jill took a liking for this slippery sport. In 2002, at the Salt Lake Winter Olympics, Jill and Vonetta Flowers brought home the gold medal in the first ever women’s bobsled event.

Now, twenty years later, and to top off this story, I screwed up my courage and signed up to ride down the Olympic bobsled track. I was tucked in right behind the driver as the 4-man sled roared down the track. We hit 70 mph and pulled about 3 g’s. At the bottom, I got out of the sled a bit shakily.

But now I had a new point of view: Sliding on ice can be exhilarating.
