Bison Pulling - a unique experience

Bison Pulling is an annual event at Mountain Meadow Wool

Yes, it is as odd as it sounds. 

Every year we are privileged with the opportunity to get up close and personal with several hundred of these 1,000 pound goliaths.  We call it “Bison Pulling” because we actually comb/pull the soft bison “down” off the animals.  Our goal is to collect this soft undercoat that the animals start to shed as the days begin to warm during late spring. 

The bison are brought through a series of hydraulic chutes made of very heavy-duty steel.  The chutes are specifically designed for this purpose and consist of a maze of gates that open and close slowly move the animals towards the final hydraulic unit.  The goal is to keep them moving slowly and to not get them excited.

The final unit gently holds the animals stationary while we collect fiber from the shoulder area.  Meanwhile the veterinarian onsite is administering necessary shots and the rancher is putting in ear tags and the ear brand.  Each bison is only in the final unit for about 30 to 60 seconds.

Our goal is as much of this soft bison down as possible.  However, in the process we will be collecting some of the courser guard hairs as well.  It makes the final products very rustic in appearance and feel but what could be more appropriate when using fiber from this iconic animal. 

Over 2 days of collecting we are left with only about 30 pounds of this precious fiber.  We then scour the fiber to remove the dirt and blend it with longer staple fine wools and alpaca to create our final yarn.  Our “Tatanka” yarn (Lakota Sioux name for buffalo) and our “Mountain Down” yarn are both made using bison fiber.  Occasionally we also make small, finished products (beanies and home décor) that show off this great fiber.

Only the 1 year old’s and 2 year old’s come through the chutes.  By the time they are 1 year old they are already 600-900 pounds and the 2 year old’s can weigh in at 900-1200 pounds.  After the bison leave the chutes they go back out to the corrals to get some fresh hay before moving back out onto the wide open prairie.

    I learned about Bison yarn several years ago at Stitches South, but I’ve never seen pictures showing what actually takes place. I did learn that Bison yarn is so expensive because of the process. Also the added properties of the fiber that make it a superb yarn.
    Thank you for showing pictures and telling more about the process. I am so happy that ranchers and other people are helping our beloved American Bison make a comeback. They are such awesome mammals.

    Loved this little peak into the world of your bison, thanks for sharing !

    thank you for sharing the article. I had no idea what was involved to retrieve the fiber from a bison. Wow.

    I live in central Ohio near a public park Darby Creek Metropolitan Park and we have a small herd of buffalo. Your article and project is very interesting to me as at the age of 80 was totally unaware that you or we can obtain fur from our majestic animals. Anxious to obtain yarn and to search for a project to display. Thank You.

    First, thank you for the gentle “chuting” of these majestic animals. It’s a lot more humane than I imagined.

    Second, I bought some Tatanka to work into an outdoorsman’s cowl/gaiter for cold weather, and it’s surprisingly soft and very unique. (Question: “This just has manly fibers, right?” “Yes, you will feel right at home diving into an icy mountain stream; only no wringing, and be sure to block it and air dry every time.”

    Now, if you could add a line of mountain lion fur (cats are always shedding, right?), I’d pay to watch that. 😉
