I follow ThatSlackLineGirl on Instagram, but I got this amazing video via my mother-in-law. While watching, you could have called me ThatSlackJawedGirl.
This woman’s name is Mrs. Glover. Sadly, that is all I could google up about her. The internet may have information on almost everything, but esoteric female explorers of the last two centuries is not its strong suite. Alas.
The other two women probably belong to the Sara or Lobi people of what is currently Chad, as those cultures tend to go with the double-lip-plate look.
