JACKSON, Wyo. (AP) — Several participants in the annual antler rush in Grand Teton National Park had to be rescued when they fell into the cold, fast-running Gros Ventre River.

One horse drowned and several and people were swept downstream in rushing water after their boat capsized on Friday.

The incidents occurred on the Bridger-Teton National Forest where people typically cross the Gros Ventre annually at midnight April 30, when winter closure restrictions are lifted on public land and the antler-hunting season kicks off.

The antler hunters who needed rescuing tried to cross the Gros Ventre with five people in a hard-sided boat and it capsized.
