It was very similar to the video. Took a number of tries back and forth to break through. It was definitely near the limit of what I could get through with full tire pressure. I was on 285/70/17's. My guess is 10psi or 15psi and it would have been a good bit easier.
You can't see it very well in that picture, but I have a hidden mount winch that is behind the license plate. So in the worst case I could have winched out. I think I was just wearing shoes, so it would have been cold and messy.
If you're not familiar with a particular spot - be careful going through on thin ice. It could be 6 inches or 3 feet deep underneath.
