A wind turbine snapped its spine and fell to the ground last weekend at the Stateline Wind Farm near Touchet in Walla Walla County.
The East Oregonian reports the toppled wind machine was found Sunday.
A spokesman for NextEra Energy Resources, Steve Stengel, said the company is investigating what happened.
The turbines are built to withstand the 60 mph gusts that swept through the region. The machines shut down when winds reach 55 mph.
It was the first of 454 turbines at the wind farm to fall since they started spinning in 2001.
