I'm pretty sure this query will generate no answer (but who knows?). USGS Bulletin 2001 is by D. E. White, C. Heropoulos, and R. O. Fournier, with the long title of "Gold and Other Minor Elements Associated with the Hot Springs and Geysers of Yellowstone National Park, Wyoming, Supplemented with Data from Steamboat Springs, Nevada", published in 1992. Within Table 1 (and so far as I can find, only there and not in the text) is a gold content of 0.0024 ppm in the hot spring deposit collected at (here's the question) "Daisey Green, Upper Basin" [sic]. Any thoughts as to just where/what "Daisey Green" is? Scott Bryan -------------- next part -------------- An HTML attachment was scrubbed...
