Spokesman Bill Sadler says a trooper at the scene reports that National Guardsmen spotted the group from the air. Rescue operations are to resume at sun-up.
Pastor Graig Cowart, who has been ministering to the boys' parents, says he was told searchers spotted a campfire overnight with two adults and approximately the same number of kids reported missing.
Cowart says the scouts' parents are "relieved and anxious" and that "there's no reason to believe that everything is not well."
The Scouts from Troop 162 in Lafayette, La., arrived Thursday at the Albert Pike Recreation Area. The search began Monday morning, after the group didn't return as expected.
