>>That has the look of a percussion mark, to me.
The shape is elipsoidal, the internal part is fractured, the envolving rock
seams, by contrast, healty.
It would be a strange rockslide.
Even if the scale of the scar is dificult to evaluate from the photo, a mass
of an average car falling at the final speed of a meteorite, would not let
more evidence on a granite surface than this, I think.
Big craters form when cosmic speed is maintained, with asteroid sized
bodies, but why are we expecting such a big thing?<<
 
If a meteor was incandescent enough to be seen all the way to the ground, we
are talking about something quite large...in the range of ten tons or more.
This also would mean when it hit, it was traveling something in the
neighborhood of 9,000 mph or faster. When something this size and velocity hits the
earth, there should be one heck of a whack...Which comes to my puzzlement...how
come there are still healthy looking plants immediately surrounding the
"bleme" in the photo? I think there probably was a meteorite dropped somewhere,
but it was nowhere near the size to be seen hitting the ground...unless a
witness just happened to be standing nearby. I also doubt any meteorite of lesser
mass and velocity produced the so called "bleme".
