State troopers responded to the scene, on Highway 530 near Concrete Sauk Valley Road, at about 9:45 a.m. after receiving a report of a serious crash.
Arriving at the scene, troopers found a 1993 Subaru Legacy completely demolished in a stand of trees. The driver was pronounced dead at the scene.
A preliminary investigation found that the man was alone in the car, heading east on Highway 530, when he crossed over into the oncoming lane, veered off the roadway and slammed into the trees. He was ejected from the car by the force of the impact.
The man was later identified as Kenneth Cousins, 20, of Darrington.
