Because of the the lighting when I took these photos, I took two different views of the back side of this oriented meteorite.  The first photo shows more detail on the roll over rim, especially on the right hand side.  You can see the impact crater on the right hand side of the second photo.  The third photo is a close-up of the impact crater.  Craters like this occur on Sikhote-alin when impacted by another specimen during the violent firey descent through the atmosphere.  I have seen a few examples of this but is is quite rare.  This is one of the most defined crater that I have ever seen on Sikhote-alin.  Also, notice that the fusion crust is very thick and quite bubbly in places.  For more information on this unusual crater feature see this link:

    These are side views of this specimen.  There are numerous flow lines in the fusion crust.

  This is a view looking straight down at the top of the meteorite as oriented in the two photos directly above.  Again there are flow lines in the fusion crust.

This is a very unique individual.  Email or call me with any questions on this rare specimen.
