Locality
Crestmore, Riverside Co., California, United States

I have dealt a lot of Crestmore material and acquired quite a bit over the years, but I have never seen a Jennite of this magnitude from the type locality, Crestmore. All of the white crystals on this specimen are Jennite. On the back of the old label Kidwell states whee his specimen originated: "1963 C.M. Jenni".....a bonus of course.
