It also still shares borders with two enclaves that are considered a part of Spain - Ceuta and Melilla. The topography of Morocco varies as its northern coast and interior regions are mountainous, while its coast features fertile plains where much of the country's agriculture takes place. There are also valleys interspersed between Morocco's mountainous areas. The highest point in Morocco is Jebel Toubkal which rises to 13,665 feet (4,165 m), while its lowest point is Sebkha Tah which is -180 feet (-55 m) below sea level.
