SIOUX FALLS, S.D. (KELO) — After a hiker survived a bison attack in Custer State Park, her daughters are sharing the story of the incident and of her recovery and resilience. Katherine and Elizabeth Lange were with their mother, Lisa Lange, in the hospital. On Monday, Lisa was hiking on Lovers Leap Trail when she turned a corner and came across a wild bison. “She called me, and we are just so incredibly grateful that her call was even able to go through. I was in complete shock,” Katherine said.
