Mike Speiser climbs down from his bulldozer for a lunch break after churning over mounds of garbage at the Puente Hills Landfill, one of the largest such facilities in the nation. Nearly 4 million tons of junk and muck, one-third of Los Angeles County’s trash, is added to this man-made mountain each year. (Gina Ferazzi / Los Angeles Times)

Mike Speiser drives his bulldozer over mounds of garbage at the landfill. “It’s kind of like laying concrete.

A trucker prepares to unlatch his load of trash at the landfill. Beginning before dawn, a parade of trucks bounces up a sinuous roller coaster of a road that’s constantly burping from the digestion below.
