The Chisago County Sheriff's Office says deputies navigated the ``extreme terrain'' to reach 19-year-old Luke Zajac from Marine on St. Croix at Interstate State Park in Taylors Falls Sunday afternoon.

Deputies used data from a 911 caller in order to zero in on the teen's location. The deputies then directed other emergency responders to the location, which was only reachable by foot.

Zajac was lowered to a safe spot, then taken by air to a hospital. His condition was not released.
