County firefighters fist-bumped each other at a slow-spreading blaze on Monday afternoon on Mount Vision Road. The fire, near Pine Ridge Fire Road, was fully contained within a few hours after burning about a quarter of an acre. Although fire planes flew overhead, they did not douse retardant owing to the fire’s small size and a heavy summer fog that shrouded the mountain. Officials said the fire was caused by people camping in the area illegally. “This brought back some eerie memories of the Vision Fire of 1995,” John Dell’Osso, spokesman for the Point Reyes National Seashore, said.
