San Bernardino Wash        34°0’2"N, 115°43’47"W

California, USA

Found: 2010

Writeup from MB 103:

San Bernardino Wash        

[additional] History: On 18 April 2012 additional stones were recovered by Robert Verish, also of San Diego, California. His first find (343.1g) was a nearly whole, slightly weathered individual stone. The subsequent stones (~650g) were all just a few meters away, forming a 20m wide “splatter zone” comprising ~24 badly weathered fragments, none of which could be physically-paired to the 343g stone.

Main mass:Verish
Comments:Submitted by Verish; Specimens: 22.1g (3 samples from the initial 10 pieces), 23g (from the 343g stone) and 41g (from the main mass); Because the 343g stone looks much less weathered, it was micro-probed by A.E. Rubin (classifier, UCLA) and characterized as being, "not only much less weathered, but also more shocked, slightly more equilibrated, and less chondrule-rich than the other San Bernardino Wash stones"
