It is interesting to note that of the cones I have listed (16), 8 of them (50%) are in the Upper Geyser Basin. One might also ask how to define a "cone." I am listing only those cones that have an arresting appearance. Low, mound-shaped masses of sinter, like those around Bulger Geyser, seem very different, almost as if they formed through a different process. Therefore I did not include them in the list. It would appear that cones are fairly rare. Any thoughts?
