This is comparing the height of the snow to the sidewalk. The snow had been shoveled into the street, so there isn't extra snow piled on top here.
So we decided to go sledding again! In some places it was too deep for the sleds, but once we got a good track for them to slide down it was great (but still very cold).
And here is Julia's snow angel. It's kind of hard to tell, but the snow was higher than she was once she sank down into it.
