[Geysers] Black Diamond area

[TSBryan at aol.com]

My thanks go along with the others for the photos and reports about the  
goings-on at Wall, Black Diamond, and Black Opal. A couple of points and  
questions here.
 
1. That "Wall Pool" sign has been incorrectly placed above Black Diamond  
for quite some time now. I long-ago pointed out the error to 
interpreter-signman  Sam Holbrook, and he said he was not authorized to simply move it to a 
correct  place without authority from a "higher-up."
 
2. The photo posted by Peggy Treat (taken in  mid-September) shows  Black 
Opal Pool.
 
3. Do observers feel (if there is any opinion at all) that the muddiness in 
 "Salt & Pepper" is due to a change in the spring(s) itself, or because of  
debris freshly washed into the crater(s)?
 
4. Is there any evidence of eruptions in either Black Opal or in any of the 
 vents in and about Wall?
 
Thanks again to all.
 
Scott Bryan
