Old Ephraim or Ol' Ephraim is a term popularized in the 1800s American west to refer to grizzly bears. More recently, Old Ephraim (known as "Old Three Toes" by sheepherders due to a deformity on one foot) was a very large grizzly bear that roamed the Cache National Forest from circa 1911 until his death on August 22, 1923. He was named after a grizzly bear in California described in a story by P. T. Barnum.
