(KSL News) -- One of two Indian sisters who brought worldwide attention to the land rights of Shoshone Indians has been found dead on her Nevada ranch.
Mary Dann and her sister Carrie battled the federal government for decades over grazing practices. They claim the tribe owns much of the land in Nevada and Utah because of the 1863 "Treaty of Ruby Valley".
Congress authorized a buyout of Shoshone land rights, but the Dann sisters refused to accept it.
Carrie Dann, Nevada Rancher, 1993: "I would never accept that money because I'm a traditional person. I beleive in my own ways. This land is earth, a piece of that land is my mother. I can't sell the very breasts that feed me."
On Friday night Carrie Dan found her older sister Mary under an overturned ATV. It's believed Mary died suddenly of natural causes and then rolled the ATV. One friend said, "She died as she would have wanted - with her boots on and hay in her pocket."
Mary Dann was believed to be in her early 80's.
