Chavez-Ravine-B4-LAD-Stadium2

Via Google images. Top: Charles Marville, Rue Champlain (Paris 1850s). Bottom: Chavez Ravine before leveling to make way for... Baseball (Dodger Stadium, LA).
I saw Marville's photo and a view similar to the Chavez Ravine photo on a recent trip to Washington DC museums. Was thinking about the similarities of terrain, socioeconomics, etc.
