A few more photos -- the pile at the end of the driveway after the first wave of snow. We worked for a couple of hours to get one side free of the heavy, packed snow (oh, our aching backs and elbows! -- and this was after someone had already cleared an opening several feet side on that side of the driveway for us early this morning) and get the mailbox clear enough for the mail truck to drive up to it. Then our neighbor who has a huge two-stage snowblower did the whole other side in about 10 minutes and promised to help with the next wave as well. We appreciate the neighborly kindness!
The snowplow heap was two to three feet deep. [Addendum: as you can perhaps see in this photo, the reason the piles are so high is because we live on a circle that gets completely cleared, so what ends up at the curb is generally much higher than you'd see on a straight road.]
The blade of the snow shovel is at least 10" high - maybe closer to 12". That's a heap o' snow!
