The Monument Geyser Basin in central Yellowstone National Park was heralded to me as a great adventure.  Here you could enjoy a geyser basin in its natural state, without crowds or even boardwalks!  Unfortunately, I’m afraid it was a bit oversold.  While it isn’t exactly popular, and there aren’t any boardwalks, it’s also not exactly a premier example of geothermal activity in Yellowstone.  However, I did enjoy it enough to post about it (here goes!), and there is one type of feature that I have not seen in any other of Yellowstone’s more easily accessible geothermal areas – smoking stacks!
