The family of an Augusta woman on a 10-day trek across Nepal has not heard from her since Saturday’s earthquake, reports Portland television station WGME, CBS 13.

Khaled Habash says he has exhausted all efforts to try to locate his mother, Dawn Habash, who began her trip through Langtang National Park on April 18.

“The last communication I had from her was April 17th before she started her trek and it’s not necessarily common to communicate on trek because there aren’t a lot of ways to communicate, but she would be towards the end of the trek at this point, “ he said.

Habash said he added his mother’s information to a Nepal earthquake website and heard from a woman on the same trek as his mother. She said people in that region are cut off, but they do have water, Habash told the Portland television station.

Habash said his mother doesn’t have a cellphone, but he’s hoping for the best.

“It’s just a waiting game at this point, but all could be well. … She could be fine and just have no way to communicate.”
