Brenna is a 2021 Trail Sisters and The North Face Adventure Grant recipient. This is her adventure story!

I’m floundering in thigh-high snow, the struggle mostly futile, trying to catch up with my field partner. We are high above Yellowstone National Park, following the three-day old GPS points of a wolf wearing a radiocollar used for research, studying its diet and behavior by seeing where it goes and what it leaves behind. She is bounding through a windswept patch, covering more ground in a second than I have in minutes. Elise and I have been friends for years, two early career women in a traditionally male-dominated field, both graduate students studying carnivores at universities in Montana. Our friendship has been forged in rain and snow, heat and bitter cold, working with wildlife, running trail races, and exploring throughout all seasons. We have dreamt of many adventures, but this one most excites us. When the Trail Sister’s Adventure Grant opportunity arose, I knew immediately we had to apply.

Brenna and Elise

We have fanaticized of traveling the eastern boundary of Yellowstone National Park, from Cooke City, MT to the east entrance of the park. This journey is a serious endeavor of approximately 50 undulating miles with thousands of feet of elevation gain and loss, and scores of wildlife that call the area home. The route straddles the boundary between Yellowstone National Park and the Absaroka-Beartooth Wilderness, a place very few people will ever see in its entirety. This is an incredible opportunity to illustrate how to respectfully coexist with wildlife in a human-dominated landscape; grizzly bears, gray wolves, elk, and many other animals are abundant in this remote region. We have dedicated our careers to the conservation of such places and want to help others travel respectfully through these creatures’ homes. We will complete our adventure in July of 2022 but this summer we scouted some tricky areas of the route. One scouting mission included the retrieval of a radiocollar from one of the wolves involved in this research project.

Wolf 1118F, a female wolf living in the heart of Yellowstone National Park, strayed into the state of Wyoming during the 2018 hunting season and was shot in the front leg. She survived for almost another year, navigating through deep snow, across rivers, and avoiding danger – all on three legs. Wolf 1118F showed her incredible spirit surviving even with such a grievous injury. During the two months after her injury, she traveled an average of 1.2 miles per day (1.9 kilometers), scavenging for even the smallest amount of food. Before her injury, she traveled an average of 6.6 miles per day (10.6 kilometers), a feat for any creature! Wolf 1118F succumbed to her injuries in September 2019, deep in Yellowstone’s backcountry.

The radiocollar wolf 1118F wore during her life held valuable data on her movements. Other groups had tried to find her and retrieve her collar containing this data but were thwarted by early season snow and numerous grizzly bears in the area. Her last known location was near an area of our route called Notch Mountain, a 10,950’ peak with a sheer cliff on one side. We were unsure if we could make it over this treacherous spot and retrieving wolf 1118F’s radiocollar would also give us an opportunity to see this remote area.

We found her on a high ridge, in a thicket of windblown trees near a mountain goat trail. Her final resting place overlooked a pristine wild area filled with steep gullies, a winding river, and alpine meadows. The grit it must have taken to climb to this spot as her final act was not lost on us as we looked towards the ridge we would be climbing on our own journey. We saw how we could move from ridge to valley, avoiding the treacherous shoulder of Notch Mountain to safely pass through the area. We were thankful to share this place and the courage wolf 1118F showed until the very end.

Coexistence with wildlife is fraught with difficulty. Wolf 1118F persevered through extreme hardship in a world filled with humans. Humans have quickly changed the world in countless ways, and we must realize that wildlife attempts to survive alongside us. There are numerous acts we can take to minimize our impact on wildlife. The most important and perhaps simplest, is by respecting their space and home. Seeing and being around wildlife can be a powerful experience, but by giving them space to feel comfortable, they can live a less stressful existence. Minimizing human interaction will let them raise their young safely and interact with each other and the world in a more natural way.

Supporting trail systems and managers that are considerate to wildlife needs and movements is a vital action as well. If your local trail system or running group does not already consider impacts on wildlife while planning races and events, the local wildlife will thank you if you bring up the subject with organizers. Wildlife exists with us, from the high alpine to within major cities to agricultural areas. On our journey along the eastern boundary of Yellowstone National Park, we will treat our adventure as one in their home, just as we try to do in our local towns and trails.

Being empathetic to wildlife by minimizing our impact and respecting the homes of these wild creatures is the greatest act of kindness we can give them.

  1. Hi. I am a member of the Facebook group, “Yellowstone Wolves,” and so I was happy to come across your article here, stating that you two ladies had found the radio collar of wolf 1118F. I read the entire article; thank you for posting a description of where you found her collar, but your article didn’t answer all of my questions, so I have included my questions here. Here is the first question: So is the man in the photo above holding the actual radio collar of wolf 1118F, or is that just a picture that you included of a radio collar to let people know what one looks like? Also: Is the place where the man is holding the radio collar the exact place where you found the collar of wolf 1118F, or is the place where “Elise” is standing in the photo (on top the mountain) the exact place where you found the collar of wolf 1118F–or is neither place the location of where you found the collar of wolf 1118F? Did you take any pictures of the exact location where wolf 1118F passed away–where you found her radio collar–and if so, can you share them with the “Yellowstone Wolves” Facebook group? (I have already shared your article with this group.) Did wolf 1118F die ON Notch Mountain, or just NEAR that mountain? She died WITHIN Yellowstone National Park–right? What specific STATE did she die in–Montana? I know that the “Yellowstone Wolves” group (and I) would like to see these pictures of the exact spot where you found the collar of wolf 1118F and pictures of the scenery that is around this exact spot, if you have any pictures of this. These next questions are sort of sad, but if you can answer them, this will give me and the rest of the group more closure: When you found her collar, did you find her complete skeleton with the collar, including her skull? What remains did you find–based on the pictures that you took and your best memories? If you took pictures of her remains, can you send (copies of) these pictures to my email address? After you found her collar, what did you do with it? Who has her collar now? If you found any of her remains (besides her collar), what did you do with them? I know that I have asked you a lot of questions–12 in all, I think–but I hope that you will answer all of them–it would mean a lot to me–and I will share your answers with the “Yellowstone Wolves” Facebook group; I know that they will appreciate hearing the answers to these questions, just as I will. Thank you for your time! Very Sincerely, Tiffany Boyd
