Yahi Artifact Collection

Yahi Stone Artifacts


This website was created in order to share my collection of Ancestral Native American rare ground stone food processing implements and other stone artifacts, which I started collecting in the early 1980’s.  I grew up working on our family farm owned by my parents in Northern California where the Yahi tribe once occupied this land.  (view map of Yahi tribe camp)

This collection is not only one of a kind, it also honors the ancestral craftsmen of the Yahi tribe. I hope you enjoy the historical value of this site as much as I have enjoyed researching these implements. (The collection is unique, serious collectors feel free to contact me).

To Whom it May Concern:

This collection of finely crafted ground stones was created by the now extinct Yahi people which included Ishi, the last know free living Native American. The Yahi were amazing craftsmen. I feel very strongly about sharing their legacy with the world. This tribe lived peacefully on the land that many years later was farmed by my family and the family who owns the property where I found the artifacts. Making it possible for others to enjoy their craftsmanship is such an honor and gift from the ancestral Yahi people. It is my dream to make this showing possible.

This collection started out as my unusual river rock collection. It began with net and canoe rock weights and other interesting rocks. This was a fun project for my kids to show at the Tehama County Fair in the 1980‘s.

The collection took on a whole new meaning when the ancestral Yahi spirits, (an indian lady holding two babies came to me in a real as life dream), entrusted me to be the one to find their very special and uniquely crafted groundstones. This small tribe of Native Americans were peaceful, creative people. Their tribe was brought to extinction by the white men of this area. I feel an obligation to her as well as a need to these people to show the world their unique life work..

The family has kept the collection safe for all of these years. My concern is what will happen to this collection if I don’t do something with it soon. The kids have all grown up and moved on. In the future, the parents will pass on and what is left of the farm will be sold. I’m afraid that the collection will be broken apart or lost and never shown and acknowledged for the amazing part of history that it is.

I need to raise approx $200,000 to acquire these special ground stones for the family whose land I worked on and found these artifacts. As the founder and part owner of the collection, I will get any money over the $200,000 that the family is asking for the collection. We need your help.

I have put many hours and money into the legacy of the Yahi people thru this collection over the years. It is my dream and goal to see this collection shown in a museum where many people can appreciate and enjoy the history and legacy of these amazing Native American people. I feel that getting this collection on display for the world to see is long overdue. It is very important to me to make sure that the collection goes to a well known museum and not a private show piece. Because of this, in the past when I was asked the price of the collection, I said $1,300,000. This was keep it safe until it could make it’s way to a museum where it could be seen by the world.

The museum that has the ability to best show the artifacts of the life work of Ishi and the Yahi people will be the one to obtain the collection. I will be contacting Dr. Jerald Johnson, retired Sacramento University archaeologist for his expert opinion.

My purpose in doing this is to help bring awareness to the wonderful Yahi artifacts and the legacy of their creative spirit. The note cards are beautifully photographed and printed on quality paper (while also keeping the cost as low as possible).
