The Big Kahuna for fall color in Southern California’s mountains this past weekend was Big Tujunga Creek near Sunland-Tujunga where Ken Lock captured cottonwood still carrying gold.
Yes Gidget, it’s past peak. Though, spots of peak color can still be found here and there in Los Angeles’ San Gabriel Mountains.
