With a fresh blanket of snow on the ground and falling temperatures, winter has officially arrived at Yellowstone National Park.

The world’s first national park is also one of the coldest. In winter, temperatures top out in the teens, and can plummet to 20 degrees below zero. With an average elevation of 8,000 feet, Yellowstone can be affected by alpine weather systems that produce bone-chilling temperatures and an average of 150 inches of snow a year.

As temperatures drop, so does the number of park visitors. Summer months see peak traffic around 900,000 people a month while winter months can have as few as 20,000.

Off-peak travel can yield fantastic benefits. In addition to fewer tourists and less congestion in the park, locals are more accommodating and willing to engage in conversation. This interaction provides an opportunity to learn about lesser-known locations and local wildlife sightings. During the cold-weather season, herds of wildlife migrate down from higher elevations in search of food and warmth with wolf, coyote, elk and bison replacing the summer visitors.

For several years, I have dreamed about navigating Yellowstone’s harsh terrain to photograph wildlife in winter. From the moment I first discovered photography, I enjoyed the challenge of capturing wildlife in their natural habitat. To capture unique photographs takes time. You have to learn the animals’ habits and mannerisms and anticipate their actions. I find it exhilarating to be alone and outnumbered by the wild species that live in the park, but to fulfill my dream, I had to deal with some logistical challenges. Only one park road remains open during winter, and accessing inner regions of the park requires cold-weather equipment.

When I arrived at Yellowstone, I decided to travel the park by snowmobile. After all, I was here to capture photographs of wildlife in their natural habitat, and that would be hard to do from inside a tour bus. I needed to be able to travel light and react quickly. If an opportunity presented itself, I wanted to be prepared.

At 5:30 a.m. I found myself walking through the cold, dark parking lot of Three Bear Snowmobile Tours in West Yellowstone, Montana. It was 14 degrees below zero. Although tours would not typically begin for another couple of hours, my guide, Chris Daniels, had made arrangements to get me into the park well before sunrise. Daniels has been guiding snowmobile tours in Yellowstone for over 10 years and knows the park well. If anyone was going to help me get the shots I wanted, Daniels was the guy to do it.

After a quick cup of coffee, we both hopped on our snowmobiles and started the ride toward Yellowstone. I could see the dim lights of Three Bear fading in the rear-view mirror. Even though we got an early start, we still had to hustle to the northwest area of the park if we were going to make it to our first stop in time to catch the sun rising over the mountains.

As we were getting our cameras set up, I could tell the day was going to be special. We were standing in deep snow on the banks of the Madison River, watching it wind its way through the landscape, around the bison and into the mountains where the sun had begun to light up the sky. With our first shots under our belts, we headed south, deep into the park in search of our next location, Tangled Creek.

I have been to Tangled Creek several times during the summer, but experiencing it in winter is a photographer’s dream. The cold air and warm water created a blanket of fog that hovered throughout the trees giving the area a bit of an eerie feeling. No crowds or noisy cars were around.

As we left Tangled Creek, the weather began to turn. Clouds rolled in, flakes began to fall, and we were excited at the thought of capturing wildlife in fresh snow. We came across a small herd of bison huddled around the warmth of some geothermal water. As they clustered together, they quickly become covered in frost. The combination of the snow and frost was exactly the shot we were seeking. The conditions were fierce, but for us, it was worth it.

As the day began to wind down, we made our way back to West Yellowstone and back to Three Bear Snowmobile Tours parking lot where we began our adventure almost 12 hours earlier. We wrapped up with a cold drink and mouth-watering burger—reliving the excitement of the day. We had endured the elements and caught a glimpse of what makes winter in Yellowstone so amazing.

Around each bend a new landscape unfolds, new wildlife emerges and new opportunities present themselves. For those who are willing to brave the harsh conditions of winter in Yellowstone, the rewards can be rich and plentiful.
