During yesterday's unacceptably hot afternoon, many Dolores Park goers stood agape a the sight of a massive fire to the south of Valencia (before saying “whatever” and heading to the park as planned).  Turns out La Lengua was't going up in flames, it was just a 41-acre wildfire torching San Bruno Mountain.  Via ABC7:

 A four-alarm fire burning on San Bruno Mountain in South San Francisco sent a large plume of smoke in the air that was visible from several miles away. Dry conditions helped fuel the blaze that was reported at about 1:55 p.m. Saturday.

Over 100 firefighters battled the blaze and stayed through the night to make sure it didn't reignite because at one point the flames were so tall, they were as high as Eucalyptus trees.

It was a full-fledged fire fight from the get go. Flames quickly ate up the dry vegetation on the San Bruno Mountain.
