Sightings of a mountain lion along the American River have prompted state parks officials to post warning signs.
There have been four sightings of the mammal this month. Two of the sightings have been confirmed by employees of the state Department of Fish & Game, which has offices at the Nimbus Fish Hatchery.
The four sightings occurred between Nimbus Dam and the Lake Natoma Crossing bridge in Folsom. There have not been any sightings for more than a week, a state park official said.
Signs went up last week, telling bike trail users and visitors to the American River what to do if they encounter a lion:
Do not run.
Pick up children.
Make yourself appear large.
Shout at the lion to go away.
Notify state parks officials.
