Still presuming that this "Nifty" is the same as "UNNG-OTO," then it probably dates to the early part of the 1980s. My recollection is that the "OTO" name ("Old Tardy-Oval") originated with (or at least I first heard from) Ann Deutch. In saying that, I also say "I think." Also, in reply to Denise Herman, probably the only decent map of the Artists Paint Pot area would be in the backcountry things done by Paperiello and Wolf. Which I have in storage somewhere and cannot retrieve right now. Scott Bryan In a message dated 6/28/2011 4:39:16 A.M. US Mountain Standard Time, stepheneide at cableone.net writes: Nifty has been pretty active the last few springs, it seems to be more active when the Sawmill system is in Penta-Churn mode but that is not required. It can erupt for over an hour several times a day when it is very active. I think (like Old Tardy) it usually erupts when the rest of the system is in drain. The times I remember it erupting I also remember Oval Pool being low. Also, the when Nifty is erupting the new hole between Nifty and the boardwalk (to the northeast) steams and you can hear if gurgle in the hole. This hole looks like a buffalo broke through the ground but it may have other origins. I don't remember how old Nifty is, maybe someone else has that data. -------------- next part -------------- An HTML attachment was scrubbed...
