Thirty kilometers away from Senegal's capital city, Dakar, sits Lac Rose, separated from the Atlantic Ocean by a few sand dunes. Colored by algae and boasting almost more salt content than, well, salt, Lac Rose has nearby stables on its farthest side, and it's toward those stables, and the horses housed there, that we're heading. Hundreds of salt collectors harvesting salt from Lac Rose dot the lake's landscape as we drive by them, almost into them, and between the hills of salt and sand.
