Dear List:

I am just an amateur, but went to the Gold Basin strewnfield in November of 2001, not only to search for meteorites but also to photograph the Leonid's meteor storm from dark skies.

I met Don O'Keeffe there, and also Bill Fisher, a gold and meteorite hunter from California. Bill Fisher told me at once that I would not find anything with my Whites XLT detector. He was right (highly mineralized ground) and he lent me a Gold Bug detector with which I searched for 2 days. I did not keep records but over those 2 days I found 6 small pieces ranging from 10 to 20 g. So, on average, that's 6 per 48 hours, or 1 for every 8 hours. I feel very fortunate that I found any at all on my first attempt at hunting.

BTW, the Leonid's storm was awesome from the strewnfield.
