DeC. 7 BEACON LIGHTING CEREMONY

Although the threat of ice and snow have forced the move of the 50th annual celebration off the mountain, the refurbished beacon atop Mount Diablo will be lit once again Saturday, Pearl Harbor Day.

Due to expected weather conditions, the celebration with Pearl Harbor survivors has been moved to Concord, but a park service worker will flip the switch at the mountain's summit at 4:15 p.m.

The ceremony with survivors will begin at 3:45 p.m. Saturday in the library at the Cal State East Bay campus in Concord, 4700 Ygnacio Valley Road.

Due to the recent restoration of the 1928 beacon and a beam adjustment, more people will see the beam this year and from further away. Activated in 1928 as an aviation navigation guide, it was meant to shine into the sky. The adjustment, and change to a brighter bulb, will allow it to shine brighter and lower so it can be seen from more communities.

With the changes, the full strength of the beacon will be visible from Concord, Pleasant Hill, Walnut Creek, Alamo, Danville and San Ramon; and it can be seen in the distant areas of Sacramento, Stockton, Tracy, Modesto, San Jose, the Peninsula, San Francisco, San Rafael, Vallejo and Fairfield.
