[Geysers] Lion and ? (N.Goggles)

[Ron Keam]

The postings on this matter lead me to ask:  Does a very detailed map 
of the locations of the springs on Geyser Hill, and indeed the whole 
area back to OF Lodge exist?  (I have a recollection of being told 
that this was the case during a very early conversation I had with 
Scott Bryan.)  If so, and if also a reasonably accurate location for 
the camera is known, then it ought to be possible quite readily to 
determine the direction of the line-of-sight to the steam cloud that 
appears to show something erupting. If the line-of-sight intersects 
the location of a thermal spring, then this becomes a prime candidate 
for the source of the cloud.  (Of course there could be ambiguities 
if more than one spring lies on the l-o-s, and there is still a 
reasonable probability that it is a Lion cloud masquerading - as 
several others have suggested.)  This is a process I have used 
several times in my own investigations of geographic features in the 
New Zealand thermal region - particularly with historical photos.
