River Otters of Northern Yellowstone in the Winter

It seems that when we make our annual winter trip into Yellowstone between Christmas and New Year’s we have a specific animal we are hoping to see and photograph. Of course, we always see bison, moose, wolves, elk, coyote, bighorn sheep, mountain goat, and fox. Well, almost always see fox. This year we really hoped to see river otters and to be able to get some good photographs of their antics atop the frozen covering of the Lamar River and the Soda Butte Creek. To see them emerge through the openings in the ice-covered waterways and engage in their playful activities is a real treat, and worth the effort to get out and hike along the rivers looking for signs of the illusive critters.

Day 1

We spent much of our time walking stretches of the Lamar River with great hopes of spotting the dark black bodies with grey fronts against the backdrop of pure white snow. Near the end of the day, we pulled into the parking lot at the entrance to Pebble Creek Campground. Pebble creek campground is located at the northern edge of what is known as Round Prairie. Our intent at this stop was purposeful as we walked over to the creek as it passed under the bridge along the northern road section hoping to spot some otters as we have previously.

We received a boost of optimism when we spotted several otter tracks with the accompanying undeniable belly slide and tail drags and whips in the snow, moving between water openings in the frozen and snow-covered creek. Unfortunately, darkness soon enveloped the sky ending our hopes for an otter encounter, and we headed back to the motel for some needed sleep in preparation for the next day’s adventuring.

Day 2

To our great delight, we were rewarded the second day, after walking a stretch of the Soda Butte Creek, with a fun filled afternoon of watching and photographing three beautiful and sleek looking otters moving up and down the frozen Soda Butte Creek. The time of day was mid-morning when we first spotted them, and they were very much on the move heading downstream with periodic stops to emerge from the water and engage in playing around on the ice and taking back-and-forth trips to the other side riverbank.

Always trying to anticipate the otter’s next move in our attempts to be strategically positioned along the sides of the creek for a great photo op, we too found ourselves on the move. We would be snapping photos and then when it appeared they were moving downstream again, we quickly drew back from the river so as not to be detected and began trudging through the snow to the next place we felt they might emerge from under the ice at one of the few openings.

At certain points along the river the otters got close enough for us to capture some cellphone footage. Often times both of us struggle between choosing to photograph the animals where we are focused on looking through the camera lens, and simply wanting to put the cameras down and fully engage in just watching the animals in their natural habitat with no distractions. Sometimes this can be a difficult choice and thankfully we try to sneak in both. However, because a photograph or video footage lives on as a tangible reminder of the experience, most of our time is spent trying to get the best photos possible.
