This is a completely new one to me, encountered today in a single reference. Unfortunately, the reference was published in 1991, and is now available online for $32 (which I'm not going to pay). But should anybody have access to the following journal, it would be wonderful. GeoJournal, vol. 23, no. 1 (January 1991) p. 73-84, published by Springer Netherlands. Now, the curious thing is that this report seems to have been part of the XIII INQUA Congress (whatever that is) dated August 2-9, 1991. So what's with the January journal? Maybe really 1992? Anyhow, the place of interest is stated as the Fenghuoshan geysers. Google Earthing found a "Fenghuoshan tunnel" along the highway/railroad (one or the other) that runs from Qinghai to Tibet. The locality is in Qinghai, well outside of Tibet, at latitude 34.7N longitude 92.9E, altitude about 16,200 feet. So should somebody have nothing else to do... Scott Bryan P.S. Yes, in that Yangbajin photo there is a pipe. Is it the source of the eruption? Maybe. <BR><BR><BR>**************************************<BR> AOL now offers free email to everyone.
