By the  way, do not confuse Rainbow Spring with Rainbow Pool---Rainbow
Spring is  well off into the backcountry, a two day pack trip as I
recall.Anyway, I  bet many of you never realized that Yellowstone had oil.
Don't spread that  around :-) ...

I don't know about Rainbow Springs, but Allen & Day noted the presence  of 
"bitumen with a tarry appearance and odor" and "tarry substance" in the  
fumaroles at Calcite Springs. Their interpretation was that this was a  distillate 
from organic material in the sedimentary rocks that lie beneath the  volcanics 
of that area (near Tower).
