Mount Baldy is a 120-foot sand dune at the southern tip of Lake Michigan, lying within the eastern end of Indiana Dunes National Park. The dune began forming some 4,000 years ago and is continually changing as a result of natural factors. During the last 175 years, anthropogenic (human caused) influences have greatly impacted sand movement at Mount Baldy, causing the dune to move inland at an unnatural and alarmingly fast rate.

Resource managers have initiated a multi-pronged effort to restore the dune and slow its landward migration. Efforts include:

  • Installing wind blocks
  • Re-routing select trails
  • Restricting visitor access
  • Installing signs
  • Public education
  • Planting dune-stabilizing vegetation

Strategic monitoring efforts are underway to track morphological changes on Mount Baldy and to assess the effectiveness of restoration strategies.
