On May 21, 2002 my nephew Larry and I left his house near Hesperia, CA and headed Northeast on I-15. We got off at the Zzyzx offramp (milepost 130). We went North on a dirt road, following the directions in the publication by Millard F. Maynard, et al from the San Bernardino County Museum. After about 6 miles we could go no further in Larry’s van, but the mine could be seen at the top of the hill (better than it can be seen in the picture above- I was shooting into the sun). I hiked the rest of the way up, while Larry turned the van around. The adit is open, but I didn’t enter it, since I had no light source, and Larry was a long way off. He could hear me hammer while working on the tailings, but wouldn’t have been able to hear me if I had gone underground.
After getting the material home, cleaning it up, and looking at it under the microscope, I found:
Chrysocolla pseudomorph after Hemimorphite
Chrysocolla pseudomorph after Aurichalcite (#983)
Chlorargyrite, var. Embolite (#985 & 990)
Numbers in parentheses refer to my price list.
There are still quite a few species known from the Blue Bell that I didn’t get:
Chrysocolla pseudomorph after Caledonite
Chrysocolla pseudomorph after Kaolinite
Chrysocolla pseudomorph after Malachite
In addition to the Museum publication mentioned above, this mine is also written up in The Mineralogical Record, Nov./Dec. 1977.
