What is the name of the large river that forms much of Washington state's southern border?
That would be the Columbia River. Back in the old days, the settlers decided on Columbia as the name of the new state that would be split off from the Oregon Territory. Someone pointed out that this would be easily confused with District of Columbia, so they named the new state, "Washington."
The river was named after that first attempt at naming the state.
