A levee built in 2003, officially to prevent garbage from washing down the ravine into the reservoir below. Human remains surfaced during the works and keep doing so after heavy rains. On 11 August 1936, Manuel López López, deputy mayor of Lanjarón, and his sons Antonio and Félix, were shot by the Guardia Cívil and Falangists and disappeared in this ravine. A third son, Miguel, was murdered further down the valley two weeks later. After the fall of Malaga, and towns of the Alpujarra and Granada coast, trucks would arrive full of prisoners, who were shot and their bodies thrown into the common graves. Some 4,000 people were killed and buried in quicklime in this ravine.
