Talk about a close encounter!

In some incredible footage, a mountain lion can be seen traversing through the snow in a Boulder backyard on Monday.

Captured by Nin Isaacs, who is from England and was visiting her mother's home, told The Know that it was "a really strange moment" when she saw the large animal outside her window.

"I thought, ‘Is this a deer?’ And then I realized, the way she was moving, my brain clicked into gear and I realized it was a mountain lion," Isaacs said.

Check out the footage of the mountain lion below:
