This one shouldn’t bee too tough. Yet another one to occupy you while you all work on yesterday’s.
I wouldn’t have the first clue as to where to start on this one! 
Is it a PRR GG1 on The North East Coridoor,at night, during a new moon, in the middle of a power outage?[;)]
(Hint: You forgot the picture.)
[(-D][(-D][(-D]
No no! It’s a PC GG1. Can’t you see the worms mating in the moonlight? [;)]
You guys are all wrong. It’s a set of white Kansas City Southern units with the red lettering badly faded going through a blizzard on that new Antarctic Transcon.
Chris, That’s a great geyser shot !!!
You’re right, I guess. It’s hard to tell Brunswick Green from PC black under those lighting conditions.[;)]
Thanks Chad. I actually got to see quite a few geysers go off while I was there, but this one (Castle Geyser) was by far my favorite. The cone is simply huge on Castle (due to it’s old age…it’s the geezer of the geysers in the Upper Basin). During the eruption, all the water that is ejected cascades down the cone. Really a neat one to watch!
I guess if I had seen Steamboat go off, that might have eclipsed it, but Steamboat erupts anywhere from every 4 days to 90 years. Still, at over 300 feet during eruptions, it must be quite a sight!
[:O] 4 days to 90 years !!! WOW that’s a wild varience. I’ve only been to Yellowstone once, but was there for a week. I love that place, it’s so awsome.
ok. Im retarded. Here it is 
South of Thermopolis Wyoming
Tennessee Pass
? west of Helper, Ut. ?
Steamboat beats Castle Geyser even with a minor eruption. ( I caught about a 60’ eruption of Steamboat a few years ago.)
While you were in Yellowstone did you happen to hear if Fan and Morter have erupted recently?
“Somewhere in the Wind River Canyon”. I won’t even attempt to guess where since I don’t remember where “there” is in this case.
In about 1973,we went visiting relatives in Shoshoni, Wyoming. I’d say this photo is taken on the footbridge over the Wind River, about 1/2 way between Shoshoni and Thermopolis?
Yep Wind River canyon again. About halfway through. Although the foot bridge is gone now.
Emma,
There were a couple Geyser Foamers (for lack of a better term) around Grand when I watched it go off. They mentioned a couple of oddities, but I don’t think Fan or Mortar were among them.
Sorry I can’t be of more help. By the bye, I’m quite envious of you catching even a small eruption of Steamboat. If money were not an issue, I think I’d head back today and camp out there and just watch that one! [:D]
