'One-in-ten-million' white bison calf born in Wyoming state park.

A rare white bison calf was born at Bear River State Park in Wyoming, with a genetic makeup that gives it white fur. The calf is not albino and is the first white bison to be born at the park. The National Bison Association says it's a 1-in-10-million event. The birth of a white buffalo calf is considered sacred to some Native American tribes, including the Sioux, Cherokee, Navajo, Lakota, and Dakota, and is seen as a sign of hope and good times to come.
