The Journey to Molar City

From Cotton Fields to Cantina Town

Los Algodones, meaning 'cotton' in Spanish, was once known for commercial cotton farming until policy changes and river damming devastated agriculture by the 1960s. The town reinvented itself around its other thriving business: alcohol. With 48 bars serving American soldiers from nearby Yuma military bases, Los Algodones became a party destination, setting the stage for its next transformation.

  • Policy changes and Colorado River damming dried up riverbeds and destroyed cotton farming by the 1960s
  • The town had 48 bars that catered primarily to American soldiers from Yuma, Arizona
  • Dr. Bernardo Magana, the 'godfather of Molar City,' was the first dentist to recognize the town's potential
