SALT LAKE CITY (AP) — A 15-year-old girl has died and a woman was hospitalized in critical condition after lightning struck the personal watercraft they were riding across a reservoir straddling the Utah-Wyoming border, authorities said. The girl and the woman were riding on a personal watercraft in a remote area of Flaming Gorge Reservoir around noon Friday when their personal watercraft was struck by lightning, Daggett County sheriff's spokeswoman Susie Potter said. Potter said the group was riding personal watercraft on a section of the reservoir known as Hideout, which is only accessible by boat and named after a hiding spot used by early 20th century train robber Butch Cassidy and his gang. A group of people at a nearby campground witnessed the lightning strike and had to move their boat out of the area to get cellphone service and call for help shortly after noon Friday.
