Trip

Basic Alpine Climb - Middle Sister, South Sister & Broken Top Traverse

This is a 4 days (5 nights) traverse in the South Sister Wilderness which will include the climb of Middle Sister (June 21), South Sister (June 23) and Broken Top (June 24). It is a back-up plan for an original Ptarmigan Traverse trip that was weathered out. Due to the change of destination, the loss of a team member and limited time for the adjustments there are no options for adding more people to the team. This trip is full.
