Forsyth County Sheriff's Investigator Jason Soles said Felicia Williamson Lane, 40, was last seen by her husband and adult daughter about 5:45 p.m. Saturday at their home, The Atlanta Journal-Constitution reported.
The names of the man and daughter were not available.
Lane's husband said he tried calling her by cellphone about 6:30 p.m. Saturday but was unsuccessful. When he and his daughter returned home some time later, he said he discovered Lane was gone -- along with camping supplies, their Jack Russell terrier, a bag of dog food and enough provisions to last about five days.
She had taken identification and a credit card but no cellphone, the newspaper reported Thursday.
Maj. Dan Jagoe of the Forsyth Sheriff's Criminal Investigations Divisions said Lane is a passionate camper and outdoorswoman.
"She frequents the Dawson Forest Wildlife Management Area and the Chattahoochee [Blood Mountain] Wildlife Management Area. She has hiked the Appalachian Trail in the snow and located lost hikers," Jagoe said.
Lane's husband reported her missing Monday morning.
"We are concerned for her safety because she has never left home like this before," Soles said.
