Each season, Yosemite provides something special to see. In the spring, it’s all about the roaring waterfalls. Summertime is when you can explore the upper elevations in the park. For autumn, the valley and other meadows provide a fall foliage display of yellows and reds that must be seen in person. And when it comes to winter, there’s a host of things you can only enjoy during this time of year that are truly a sight to behold. Here’s some of our favorites.

Winter Phenomena of Yosemite Falls



At 2,425 feet tall, Yosemite Falls is of the many primary icons to see in Yosemite Valley. In spring, as the snow melts in the upper elevations of the park, the booming rush of water from Yosemite Creek as it plummets down from it precipice on the north rim can be heard throughout much of valley like a California grizzly roaring. Winter, on the other hand, provides a treat that can only be seen in the coldest months: a snow cone.

Every year at the base of the Upper Yosemite Falls, a mound of snow and ice forms that resembles an upside-down snow cone. We’re not talking a few feet, but rather in the coldest years, it forms into one that’s HUNDREDS of feet tall.

Frazil Ice in Yosemite Creek

Another phenomenon that happens on Yosemite Creek is frazil ice. Defined as a collection of loose random ice crystals formed by supercooled turbulent water, the definition doesn’t even begin to paint a picture of just how “cool” it is. Imagine the world’s biggest slushy machine and that’s what frazil ice looks like. Due to Yosemite Falls' massive flow, it creates these ice crystals which aren’t ice or snow, but a concoction that’s something in between. One word: Awesome!


Coyotes & Snow – A Natural Ballet of Hunting

Just like other animals that are awake during the shorter days of winter, coyotes grow a nice fluffy coat to help them survive the cold. During this period, they are constantly on the move. Roaming up to 100 square miles searching for food, the blanket of white makes it more difficult for them to catch the small mammals they hunt. This is because these critters tend to bury themselves in the snow. Luckily, coyotes have mastered a technique that’s called “mousing.”


Being strong diggers with amazing hearing and a sense of smell like a blood hound, coyotes are able to find a gopher, squirrel, or mouse deep within the snowpack. And when the top of the snow is firm, that’s when it gets interesting. This canine will rear its legs into the air and slam its front paws breaking through the firm layer. Then using its nose and paws, it will locate and catch its prey. An impressive and effective hunting technique.


Snow Bathing Ravens

Did you know that when it comes to intelligence, ravens rank up there with chimpanzees and dolphins? In fact, they’re known to communicate to coyotes of potential live prey or carrion so that they both can benefit. After a raven has eaten its fair share, they’ll clean themselves with a good bath... especially after it snows. A unique sight to keep your eyes peeled for in the wintery months.

So, grab that coat. Throw on some gloves. Put on your hat and visit Yosemite in the winter to see all the wondrous sights and sounds that only this season can provide.
