This live camera is awesome, and even more so because I just had a very strangely similar bear experience, parallel to this one in MN.
On Tuesday morning this week my doggie Jorja went on her daily walk-about and when she failed to return I went looking for her. After several minutes I found her sitting by a large debris pile on my property, made of branches, tree limbs, grass and dirt. I noticed that Jorja's head was cocked and one ear was up as if she was listening to something.
I walked over to Jorja and I saw her looking into an oval shaped opening in the debris pile. I could only see about one foot into the opening, then only darkness, because the sunlight hadn't yet reached inside. I heard high pitched muffled grunting sounds of two or three little ones coming from within. At first I thought it might be a coyote or fox den with babies but I was pretty sure that this ain't the birthing season.
Well, I was perplexed as to what animals were inside and not wanting to disturb the scene anymore I tip-toed away with my dog, and we walked home.
Later that day I told the wife of my interesting encounter, so she decided to investigate for herself. She came back shortly and all excited, explaining that she saw the opening, heard the vocalizings, and within the den she saw the dark backside of a bear. The bear apparently had situated her body in this fashion in order to block the opening.
Now I realized that the darkness I observed was probably the dark flanks of the bear. Anyways, this was a really cool encounter for us......... and now, we anxiously await the spring.
