This is only one of three stones from the Sutter's Mill fall collected before the rains of April 25th (see http://asima.seti.org/sm/). This rare beauty joins several others from this fall at Arizona State University, including pieces of SM6, SM8, SM38, SM41, SM49, and SM65, totaling ~ 27 g. Intensive research is currently underway on the ASU material, although you will have to wait a few months before I divulge any details. The red material on this stone is of an unknown origin. It is also present on SM49 (see my Sutter's Mill images at http://www.flickr.com/photos/meteorite_scientist). The red material does not appear to be from terrestrial weathering as it is present below the fusion crust on SM49.

The red material appears to be a baked layer present underneath the fusion crust of most specimens, as well as on external surfaces that were heated by atmospheric entry, but not enough to cause the formation of a fusion crust. It can also be seen on SM25, SM52, and many other stones from the fall.
