During the Great Depression in the United States, many unemployed Americans simply left the city and went back to farm life, sometimes living with relatives.
The surface of the country is naturally divided into five clearly distinct zones: (I) the series of volcanic peaks which extend parallel to the Pacific at a little distance inland; (2) the plains and lakes of the great depression which lies to the east of these mountains and stretches from sea to sea, between the Bay of Fonseca and the mouths of the San Juan; (3) the main cordillera, which skirts the depression on the east, and trends north-west from Monkey Point or Punta Mico on the Caribbean Sea, until it is merged in the ramifications of the Hondurian and Salvadorian highlands; (4) the plateaus which slope gradually away from the main cordillera towards the Caribbean; (5) the east or Mosquito coast,with its low-lying hinterland.
