Connor, Rowan and I went for a hike to Heart Lake from the Thimbleberry Lake side. There was plenty of snow on the ground and Heart Lake was entirely frozen. Thimbleberry Lake had a bit of open water near the outfall. In addition to the Ring-necked Ducks and Mallards we saw on the open water, there were at least 11 Trumpeter Swans at the upper end of the lake, barely visible against the snow.
