1 1 /2 months ago I went MTB in the snow, I don't remember the exact depth, it was at least 6", could have been as much as 10" but I think it was 6" or 8". It was dry snow. I started on an asphalt path and didn't get more than a few feet. I was trying to pedal and the back wheel was spinning until I fell. I kept trying and trying and fell 6 times.

How deep a snow fall in unbroken snow can you MTB in? Does it matter if dry or wet? Dirt or asphalt?
