View of the Colorado immediately downstream of Glen Canyon Dam (right). The green, clear water is caused by the dam trapping sediment, which would naturally cause the river to have a reddish-brown color.

The dam is named for Glen Canyon, a series of deep sandstone gorges now flooded by the reservoir; Lake Powell is named for John Wesley Powell, who in 1869 led the first expedition to traverse the Colorado River's Grand Canyon by boat.

Note that the Little Colorado is a light brown color caused by recent cloudbursts, while the Colorado is an emerald green. When Powell and his crew arrived here in 1869, it was this color of the river that they saw, while the Colorado's green color is caused by Glen Canyon Dam trapping sediment.
