could see my deep footprints and wonder why the heck this happened. then a couple of weeks later, after of course more rainy days, i noticed a large hole had opened up there. the area is above a muskrat tunnel and den area. i knew there was an underwater muskrat entrance not too far away, but it never occurred to me, or probably to the muskrat, that the continuing rain and rising lake level was going to affect his home, or one of his homes. (they have more on the other side of the lake.) the muskrats made it through the hard winter, but i have not seen any lately.
