Two sisters missing for 13 days say they survived in a remote part of Michigan's Upper Peninsula on love for their family, drinking melted snow and eating the Girl Scout cookies and cheese puffs they had in their snow-crippled SUV.

Fifty-two-year-old Leslie Roy of Valley, Nebraska and 56-year-old Lee Marie Wright of Depew, Oklahoma said in a statement Saturday that "through the days and nights while in the woods" those and other things helped them "to stay alive for 13 long days."

They were found Friday afternoon by a police helicopter pilot who noticed a reflection of sun glare off the windshield of their SUV. They are said to be in good condition. "Once we started to circle they got out of the vehicle and started waving their hands and were trying to build a fire quickly to signal to us that they were down there," said Michigan State Police Sgt. Brent Rosten, who added they were a "little weak," but "alive and well."

The sisters got stuck in the snow April 11th in a remote area of Luce County near Crisp Point about three miles from Lake Superior after checking out of a motel in Ishpeming where they had visited relatives. They had planned to drive to Mackinaw City, but didn't arrive.

The sisters stayed with the vehicle. The area where they got stranded has no cellphone service. “We were in pretty dire straits," said Leslie's son, Dennis Roy. "We knew that we need to find them soon in order to have a happy outcome."

Dennis said when technology fails, human instinct and drive to find his mother and aunt kicked into high gear. “At the end of the day it wasn't any technology trick or checking any type of records that ever got them found, (just) keeping our eyes peeled."
