This photograph of Hacienda El Progreso was taken in 1888 (or maybe in 1891) during a scientific visit by the "Albatross." It shows workers in front of their houses in the village to the east of the hacienda house. In the background can be seen the cleared landscape with fenced pasturage. The high mountain on the horizon is Cerro San Joaquin.
