When you hear the word "river," you probably picture a majestic body of water flowing through a natural habitat. Well, the LA River looks nothing like that. Most people who see it probably mistake it for a giant storm drain. It's a deep trapezoidal channel with steep concrete walls, and a flat concrete bottom. Los Angeles was founded around this river. But decades ago it was confined in concrete so that, for better or worse, the city could become the sprawling metropolis that it is today. All these years later the county is still grappling with the consequences of those actions.
