That happened to me once with a 2 1/2 foot diameter eastern white pine. They seem to fall slowly when you are far away, or perpendicular to the fall. But, when it’s coming at you, they move real quick! I dove into the snow, and a couple of huge branch stubs (which would have gone right through me) were on either side, holding up the trunk. No harm, no foul, right?
That being said, after safely taking down a couple dozen trees, I took down a 18" trunk ash, over 50 feet high.
For some stupid reason I waited a bit too long to start moving and instead of going to the side, I chose to outrun it.
I had the same experience as you did. There were broken limbs driven in so deep I needed a pry bar to get them out. If I had fallen, I would have been speared. I lost the race but all that hit me were some thin branches at the top.
I still don't understand why I made such a dumb move.
