Elysian Valley: Clear, Dry Mornings Make Particulate Matter Evident

Photo: Diane Edwardson, January 3, 2012, 7:56 AM.  You can see the heavy concentration of particulate matter hanging in the air above Elysian Valley & Cypress Park on dry, clear mornings.  Shot from Corralitas Drive.  (Click on photo to enlarge.) The Metrolink Central Maintenance Yard appears to be the primary culprit in this photo as there was no traffic on the 5 Freeway Tuesday morning.
