Thanks. I found a YARTS schedule, and there's a bus that stops at White Wolf, but only once per day, and only on weekends after September 1. That constrains my possible schedule quite a bit, but it could still work. Otherwise, as you say there's always hitch hiking.
YARTS schedule (White Wolf Lodge is stop 223):
