March 8, 2017 (La Mesa) – Rebecca Jefferis Williamson sent in this photo of trails left by airplanes over Mt. Helix, taken from the Fuerte Street bridge this morning. Some have called these chem trails but they are actually simply water vapor that has condensed/frozen due to cold temperatures high in the atmosphere. The scientific name is contrails.
