Good points.

The video available in post 20 shows this to be the area of the debris impact. There are people visible in the video which give scale to the size of debris. These are very small pieces.

At least they have recovered one of the recorders. This is a strange one. This does not look typically like flight into terrain. It does show characteristics of a high speed impact and the terrain may have masked the debris field "flow" you would expect to see as the plan skids on the ground in the direction of impact.

I still don't see anything from the video that would indicate scorching from fuel burn. It appears that the dark rocks in the gulch are a terrain feature.
