Veterinarian Scott Smiley, right, watches as four wild horses make their way onto Wild Horse Island in Flathead Lake on Tuesday afternoon. The mares were ferried to the island by barge where they joined two geldings already inhabiting the island. Seventeen years have passed since any horses have been placed on the island. Lyle Heavy Runner, of Great Falls, and State Sen. Brad Hamlett, of Cascade, donated the horses and Robert Lee donated use of the barge.
