This wasn’t quite terminal velocity, but would have still been bloody fast. A fall from 15000 feet. The chute came out but was snarled and didn’t open so the drag may have slowed him a little.
So a bunch of blackberry bushes works, he retained consciousness and only broke his ankle.
So the option would be if you were lucky enough to fall into a forested area with lots of skinny branches they would theoretically do the same as the pile of empty cardboard boxes in the stuntman movie trick. Just thick enough that each one slows you down a little without being thick enough to do damage.
Another option that could work (any engineers around to tell me I’m an idiot?) would be a large net strung over a valley or chasm with Bungy cords. So when the person hit the net, they wouldn’t stop but their force would cause the bungy cords to stretch, slowing the deceleration and absorbing the impact.
