There were sheets of ice in the inner harbor, between the Toronto Islands and the shore, and filling in all the docks along the shoreline. Further out, however, most of the lake was free of ice. We had good views of downtown from the air - I took a photo or two.
Although the sun had mostly set, I could tell from passing over the dark shadows Berkshires and the thread of light spangles heading north where the Pioneer Valley was. Although I was close enough to see the area where my alma mater lies, the weekend was too short to pay it a visit. The Berkshires were dark because, although covered in snow, they are even more thickly covered in trees which keeps the snow from doing an effective job of whitening their slopes.
I could see the darkness of a lake where the lights of the city below stopped in an even line, but it took me at least ten more minutes to figure out what it was I was looking at. It wasn't the Niagara-Hamilton shorelines - given we were approaching from the east, the lake was lined up all wrong for that. Eventually it became clear that that had been Lake Erie - we passed over Buffalo and then the glitter of the industries of Lake Ontario's western shore became clear. Toronto from the air at night is endless - largely gridded, the roads stretch out beyond the eye's reach, into the northern reaches of southern Ontario.
