Hahamongna is a Native American village site at what's now the base of JPL (Jet Propulsion Laboratory) and currently threatened by an overly-elaborate plan to renovate Devil's Gate Dam. This plan involves defoliating the area. Alternative plans would spare the ecosystem; however, the more grandiose one seems to be favored because more money is involved.
Those interested in a more sustainable approach to cleaning Devil's Gate Dam are encouraged to contact their city council members (if residents of Pasadena) or Supervisor Michael D. Antonovich (if residents of Los Angeles County).
The Arroyo Seco Foundation conducts regular tours, not only of Hahamongna Watershed Park (known for many years as Elk Grove Park) but the surrounding areas, identifying the many uses of local native plants. Participants of the 4th Annual Hahamongna Walkabout (and Bikeabout) learned about local Indigenous culture and got to eat pancakes made from local acorns and sample chia seeds and elderberries.
