Stewart Valley is a DCA (dense collection area) that is located in the arid reaches of the California-Arizona border. Over the last decade plus, thousands of small fragments of individuals of different types have been found mixed together this area. As of this writing there have been two dozen classifications from this region and all of them have been ordinary chondrites - H, L, and LL types.
The specimens being offered here were found by meteorite hunter Larry Sloan from the Stewart Valley DCA. They have not been classified yet. Judging from appearances and degree of magnetic attraction, this is definitely an ordinary chondrite, but I cannot determine which exact type.
