This is the third sighting this year of a Mountain Lion in this area.
Most lions are very secretive and non-confrontational, but mother cats can become aggressive defending their cubs. Hikers, bikers and runners, be aware and careful, keep your dogs on leash, don't go alone, and avoid trails at dawn and at dusk when the lions are on the move. In California, there has never been a documented lion attack on a horse with a rider aboard, but there has been one report of a lion tracking and following horses on the Pioneer Express Trail.
