Thin ice covered a substantial part of Swan Lake around the edges.
It has been chilly the last couple of days, with partly cloudy skies overnight, but I still was a little surprised to see how much of the surface of Swan Lake was covered in ice. It was thin ice, though Mallards were able to land on it without breaking through. At this rate, perhaps it will be another winter like last, where the lake froze up at the end of November and never completely thawed until at least March or April.
Stems of Yellow Pond-lily (Nuphar polysepala) stick through the ice at the edge of Swan Lake.
