In 2015, we branched out from cattle into raising domesticated yaks. We bought our starter herd from Spring Brook Ranch in Kalispell, Montana. We also bought our first yak from Pack River Yaks in Sandpoint, Idaho. We are grateful to both ranches for getting us started, and for their assistance in breaking into the wonderful world of yaks!

Honorary Yak



In Memoriam

Sierra Valley Yaks Kayak

B116 SBR Kayak 

5/14/2014- 1/30/2022

P112 Chet x Y102 Cher

Kayak is the foundation of our herd. He got us started in 2015 and sired many of our best yaks. He was the most perfect bull we could ask for.  He was gentle and sweet with not a mean bone in his body.  He was always up for treats and would be patient until it was his turn.  Kayak was born in Kalispell, Montana but he became a true California gentleman.

We miss him so very much.  

Y114 SBR Willy 


SBR Royal Gold Allante x SBR K011

We rescued Willy in the summer of 2018.  He was living in a very hot part of northern California with a small herd and the owners contacted us to ask if we would take them.  When we arrived at the ranch, we were shocked by his grandeur.  Willy was a stunning bull- large with a huge horn spread and a big, beautiful blocky head. He quickly fit in with our herd.  We were able to research his lineage and realized he was a foundation bull.  As soon as we determined who he was, we immediately made him part of our breeding program. 


His legacy lives on in our breeding bull SV Peanut, who is equally stunning.

SV Kali


B116 Kayak x Z174 Sandra

Kali was the first yak born on our ranch and of course, she was born while we were in Kalispell, Montana picking up a load of yaks from Spring Brook Ranch. As we were pulling into our driveway, we looked over by the creek and saw SV Sandra with a tiny black blob standing by her.  Greg slammed on the brakes and we both looked at each other in shock. We had a baby!
