Geography of Haiti
The Cul-de-Sac (Haiti) or Hoya de Enriquillo (Dominican Republic), is a remarkable valley, with a west-east direction, of low elevation (on average 50 m with some points below sea level) and with the Êtang Saumatre lake in the eastern end, on the border with the Dominican Republic. Port-au-Prince is on the western end of this valley.
