This book makes a brief history of historical archeology in Latin America and then its shift towards urban archaeology, highlighting the difference between the two. Then it analyzes the process of formation of the urban land of Buenos Aires, its fillings and cuts of the topography in the search for a flat and horizontal surface to satisfy idealized literary desires. The use of garbage and rubbish in large quantities is analyzed, to later divide the land and sell it, generating problems in the future with uncontrolled landfills. Then the three cases are analyzed: that of the town-neighborhood of Belgrano and its garbage dumps, the construction fills with rubble and the areas whose level has been lowered.
