(plural snow drifts)
- An accumulation of snow caused by wind currents, typically much deeper and higher than the depth of snow that fell directly.
- We had two feet of snow fall, two days ago, but when I drove off the road about five hundred yards into the forest (thinking I was still on the road) I lost my car in a twelve foot deep snow drift. When I returned two days later it was under another eighteen feet of snow...the tow-truck's fifty foot winch cable couldn't get it out of the snow drift until spring.
- first down
