Winter photography is usually so much subtler than all other seasons, especially fall with its bold colors. Landscapes are devoid of color and everything is white and clean. Lots of distractions are buried in snow.
There are a lot of subtle details in nature too, like in this abstract photograph of snow on Winter's Pond. A snowdrift formed along the banks and this is a close up photograph of the interesting shape of the drift, the curves that wind created, and the surface texture as the snow rolled down the funnel-like shape. And the interplay of light and shadow nicely highlighted that texture.
