I'm figuring Lake Powell as well. 186 miles long. It's like the Grand Canyon filled with water. Well it used to be filled, but the water level Is down considerably anymore. It actuallly is a portion of the Colorado and San Juan rivers up stream from the Grand Canyon. The southern few miles is in Arizona. But it is mostly in Utah like ThisGuy said. Cool place!

Its actually Lake Powell in southern Utah.

its in greece probably milos island

Nice view where is that place anyone know?
