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.

    Hello My Mountain Meadow Friends,
    LOVED the bison pulling article! Could you collect more wool if you had more hands to help? I’d come and I bet there are others who would make a dash for Wyoming with an excuse as good as this.

    Can’t wait for my next wool club delivery! Here’s to all your fine work!!!

    I loved hearing about this process . It is very interesting and I like to learn about where fibers come from and how they are made. I ike to see the animals as well and know that they are treated with care. Thank you!

    I live near the Wichita Mountains Wildlife Refuge in Oklahoma. I enjoy watching the buffaloes roam the prairie here but I don’t believe any fiber harvesting is taking place! Interesting process, thanks!
