I don't know if digital cameras come in black and white, but they might as well, considering these images. I told you I was in Yellowknife for a week but I haven't had time to tell you about it yet.
A snowflake on a black parka. Where I grew up it was so wet that the snow usually fell in moist clumps, making snowflakes like these something I saw only in cartoons. I thought the sixfold geometry existed only at the microscale. I still smile when I see big snowflakes like this for real.
I took this picture lying on my back inside an igloo. You are looking up through the ventilation hole at the top, and light comes through the not-very-thoroughly packed spaces between the snow blocks.
It is hard to digitally capture the depth you can see looking down through the clear lake ice of an ice road. In three dimensions, the imperfections in the ice show how deep it is, because you can see the fissure lines reaching away into the darkness below.
Ptarmigan are white in the winter and dark in the summer. It seems that they don't like to fly much. This one kept sinking neck-deep into the snow and still walking.
