Description: Three islands in Snake River here became one of the most famous spots on the Oregon Trail. Emigrants had to decide whether to cross the river or endure the longer, drier, more difficult trail on the south bank. Crossing the river here gave pioneers a shorter route, more potable water, and better feed for livestock.
