History of Expedition Island

Expedition Island is a National Historical Site due to its role as the starting point for two expeditions down the Green and Colorado Rivers led by Powell in 1869 and 1871. Powell began both trips near Expedition Island and mapped the river system, successfully documenting the Grand Canyon.

It’s generally considered that on these expeditions Powell completed the exploration of the last, large unknown land area in the continental United States.
