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

Leslie Roy and Lee Marie Wright 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."

The 52-year-old Roy from Nebraska and 56-year-old Wright from Oklahoma were found Friday by a police helicopter pilot who noticed a reflection off their SUV.

The area has no cellphone service.

The sisters got stuck about 3 miles from Lake Superior after visiting relatives. They wore layers of clothing and drank melted snow during the ordeal.
