The big cat was spotted near California Way and Summit Way about 6:35 p.m. in the area of Emerald Lake and Easter Bowl, Bay City News Service reported Friday.
Mountain lions allegedly prefer to avoid confrontations, but county officials are warning residents to avoid problems and keep away from the big kitties.
Mountain lions are crepuscular, meaning they are most active at dawn and twilight, so residents are advised not to jog or hike at those times, San Mateo County officials said.
