(AP) — Rescuers credit a digital camera for finding a father and son who became lost while hiking in northwest Nebraska.

A man and his teenage son, both from Lincoln, were hiking Thursday when they got lost in the Toadstool Geologic Park area northwest of Crawford.

When they didn’t return, the man’s wife sought help.

Authorities from the sheriff’s offices in Dawes and Sioux counties responded and formed search teams.

After about two hours, a team spotted flashes of light in the distance. When searchers investigated, they found the father and son. They were using a digital camera flash to light their way.

Dawes County Sheriff’s deputy Scott Swickard says the hikers, whose names weren’t released, became turned around in a thunderstorm.

They suffered only bumps and bruises.
