Momma Fox Guards her Den

I knew about the location of the Den and had visited once before the day this photo was taken. A grey , cool Spring day, I waited for a little while from a distance (this image is cropped significantly) and she made a brief appearance as she came up over the rocks near her den for just a split second or two. As quickly as she appeared , she was gone again. our eyes met only briefly. I managed to get two or maybe three frames off before she disappeared. I thanked her and went on my way wondering if I had an image that was sharp and in focus!!
