The Cottonwood overlook is a location in the Mojave Wasteland in 2281. The once-popular scenic overlook is now an abandoned promontory, offering an unobstructed view of the Legion camp at Cottonwood Cove below.
The radioactive waste truck can be opened in order to spill the barrels onto Cottonwood Cove below. This is for an optional part of the quest Eye for an Eye.
Cottonwood overlook appears only in Fallout: New Vegas.
