Honsal noted that the girls had spent the last two days in "rugged territory", and speculated that outdoor survival training they received from their 4-H club could have possibly played a part in their safe recovery.
"This is an absolute miracle", Honsal said.
Leia Carrico, 8, and Caroline Carrico, 5, vanished outside Benbow, north-west of Sacramento in the United States on Friday at 2.30pm. She went looking for them with neighbors and friends before calling the sheriff's office three hours later. Caroline was last seen wearing a maroon colored rain jacket with white horses on it as well as blue jeans and pink rain boots.
Two siblings, Leia and Caroline Carrico, aged 8 and 5 respectively were found safe on Sunday after being declared missing for 44 hours.
"With the help of the volunteer search and rescue, technical rescue, Sheriff's office, local volunteers, and multiple other agencies my girls were found after 44 hours".
Honsal said first responders provided them with fresh warm clothes and water.
"To have a positive outcome like this is just absolutely wonderful", Honsal said.
"I have to tell you that when we go the first word that the kids may be safe, there was still a question mark in a lot of people's minds", Fennell said. "These girls definitely have a survival story to tell".
The National Guard and the U.S. Coast Guard are helping in the search, which includes the use of helicopters and dogs.
Humboldt County Sheriff William Honsal said at a news conference on Saturday, the girls had asked their mother to go for a walk in the afternoon and the mother did not give them permission.
Boot prints and granola bars were found in the search area on Saturday, Humboldt County Sheriff's Lt Mike Fridley said on Friday. "The initial assessment was that they were dehydrated, they were cold, but they were well".
"The wrappers showed us a direction from where they started to where the wrappers ended up at", Fridley said.
She said "no" but noticed soon after that the girls were gone.
