In the video, the mom and her two babies can be seen on the Williams' property. They have several cameras set up at their mountain cabin.
Some of the cameras also captured a large mountain lion on the prowl Saturday night.
The Williams' say they have two streams and five ponds on their property, making it a popular place for wildlife to stop and cool off, and get a drink of water.
