Brian E. Felstet, 49, died at the scene of the crash, 26 miles north of Medicine Bow in Carbon County. He had been traveling north when he failed to negotiate a right turn in the road at about 8:20 p.m., the highway patrol said.

The bike crossed the center line, traveled over the southbound lane and off the road. Felstet and his passenger, 37-year-old Kerensa K. Smith, were thrown from the motorcycle.

Smith was taken to Memorial Hospital of Carbon County in Rawlins for treatment. Both she and Felstet were wearing helmets.

The cause of the crash remains under investigation.

Felstet was the 47th traffic death in Wyoming this year.
