A hiker reported seeing a mountain lion in the Portola Valley area Saturday morning.
The hiker said he spotted the big cat shortly before 11 a.m. in the area of the Windy Hill Open Space Preserve, approximately three miles from the Razorback Ridge trailhead, San Mateo County sheriff's deputies said.
Deputies who came to the area were unable to locate the mountain lion.
If you see a mountain lion:
■ Pick up small children
■ Do not approach it, especially if it is feeding or with offspring.
■ Do not run. Face the animal, make noise, throw rocks and try to look bigger by waving your arms.
