There are four distinct tracks from just before the berm and then going up the berm.
Possibly each track is made by one bogie -- or each track is made by the wheels on one side of a bogie -- can't say for sure without measurements, but I'm beginning to suspect we're looking at the tracks from all four bogies.
Perhaps somebody can supply the width and/or height of the berm.
So the wheels went up to the top of the berm.
Past the berm the wheels either:[list=1][*]rolled down the opposite side until the fuselage met the top of the berm and were held off the ground for a distance until the remaining fuselage failed[*]arced in a flattened ballistic trajectory until the rear fuselage collided with the top of the berm[/list=1] The grey debris pattern in front of the berm is consistent with reports of the tail breaking off at the berm, but absorbent material is possible.
