Where before there was river. This area about 30 years ago was covered by the river. The remains and the rubble of the demolitions of the city were poured to this place and gaining ground to the river. Thus this land was gradually annexed to the island Demarchi and declared an ecological reserve. Today is an area of wildlife protection and recreation. It is common for small cliffs to occur landslides. The night before the photograph, one had happened. And the moment to take the photo a park ranger warned me that I should not approach because it was very dangerous. Demarchi island. Ecological reserve. Buenos Aires city coast. Argentina.
