Jackson, WY – A holiday hike in the Tetons turned into an ordeal for three family members Sunday. All three were injured when they fell through an opening in a snowfield in Grand Teton National Park July 4th. All three were able to dig themselves out and one of the trio was able to hike out and notify rangers. Rangers then mounted a helicopter rescue of the other two. Officials remind hikers and climbers that as snow continues to melt, be cautious where snow is poorly packed or water flows underneath. And beware of areas where rocks and fallen trees cause snow to melt unevenly.
