The Toyon Canyon Landfill was a controversial landfill wholly within Los Angeles' Griffith Park. Filling began in 1957 and ended in 1985. A lawsuit in 1959 attempted to stop the project but was unsuccessful. A summary of the lawsuit is available here. There was a move in the 1980's to expand the landfill into Royce's Canyon, but that was defeated.
Currently, landfill gas is collected from the decomposing waste and used for power generation. The landfill is currently managed by the Los Angeles Bureau of Sanitation which plans to have low intensity open meadow area intended for passive recreational activities.
The landfill is clearly visible from the California Rte. 2 and Interstate 5 freeways in Los Angeles and from the surrounding hillsides, of course.
It's also dramatically visible on Google Earth. ( 34° 8'38.36"N 118°18'6.29"W) or here.
