Stony Ridge Observatory

Stony Ridge Observatory is an astronomical facility located on a ridge in Angeles National Forest at approximately 1730 meters elevation overlooking Devil's Canyon. The site features a substantial telescope that enables observers to study stars, planets, and other celestial objects.

The facility was established in 1957 by amateur astronomers and initially housed one of California's largest telescopes for that era. It contributed to significant lunar photography projects and has since grown into an important center for ongoing astronomical research.

The observatory operates as a gathering place where amateur astronomers share their passion for studying the night sky together. The location has become a community hub where people of different backgrounds meet to observe celestial objects and exchange knowledge about astronomy.

Access requires a long drive through mountainous terrain, so visitors should expect winding roads and variable weather conditions along the route. It is helpful to check current road conditions before visiting and plan extra time for the journey.

Three asteroids were discovered at this location, with one named after the site itself to honor those who founded it. These discoveries underscore the scientific importance this observatory held for astronomical research.
