I was hunting one day in late December or early January, really cold, and the marsh was frozen over solid in front of me. The dogs jumped and headed my way. A doe came by me just out of buckshot range, and walked out onto the ice.
Her back legs started to slide apart. She did the splits and sat right down on the ice. She wiggled around and got her back legs under her again. Then she slipped again and sat right back down, wiggled her way back up, and sort of tippy-toed out to a beaver hut in the middle of the marsh, climbed up ontop of the beaver hut and lay down.
The dogs came along, hit the ice, and went on across the beaver pond barking up a storm. Never saw or smelled her apparently up there. After the dogs went out, she climbed down, then went on across the marsh the other way.
