The Eye of Diablo
How to experience the Jewel of the East Bay to its full effect.
The "Eye of Diablo:" an aerial navigation beacon at the peak of Mt. Diablo, looks out on one of the finest views in the world.
First installed by Standard Oil Company to assist in commercial aviation, it was originally lit by Charles Lindbergh in 1928. Eventually, the mountain's beacon was extinguished in 1941, shortly after war was declared on Japan.
Since 1964, The Eye of Diablo is ceremonially lit once a year on December 7th, to honor those who lost their lives at Pearl Harbor creating a truly humbling and inspiring sight that can be seen throughout most places in Concord.
Now, volunteers and staff with Save Mount Diablo will light it from sunset to sunrise every Sunday in response to the COVID-19 pandemic and to honor the heroes during this global pandemic.
Mount Diablo itself is an unmistakable landmark in the State of California and boasts the largest view shed in the western United States. The view from the summit encompasses 80,000 square miles, and includes 60% of California.
The mountain is also a geologic anomaly. The double pyramid twin peak formation comes from volcanic activity and the compression caused by shifting tectonic plates. The volcano lies between converging fault lines and continues to grow at a rate of three to five millimeters a year.
To experience this all seeing eye’s spectacular and sweeping views for yourself, climb to the summit of Mt. Diablo, and pay a visit to the recently refurbished Eye of Diablo. Just make sure it is on December 7th for the full effect.
