For more than half a century, Mardy Murie lived beneath the spidery ice crystals and the ghost trees of the Grand Tetons.  Some say she is a treasure in these mountains.  She and her husband, Olaf, wrote their names across the history of conservation in America. They came to the Tetons in 1927.  Raised a family in the wilderness following the dwindling elk herd.  Their research saved the elks for all time.
