In antiquity, Egypt had been considered part of Asia,[citation needed] with the Catabathmus Magnus escarpment taken as the boundary with Africa (Libya).

This area encompasses a large watershed, forest and mountains in the northern portion of Colombia's Chocó Department and Panama's Darién province.
