Federation colony, site of a major disaster. Young Beverly Howard and her grandmother, Felisa, were present to help survivors. Traditional medical supplies quickly ran low, and Felisa learned how to use herbs and roots as medication despite the fact she was not a physician. She passed this knowledge down to Beverly, inspiring her to a career in medicine. (TNG: "The Arsenal of Freedom")
- The exact details and circumstances surrounding Arvada III were never established. Picard simply recalled it as a "terrible tragedy," so it is unknown what type of disaster afflicted the colony.
