The christening of the hot springs and geysers of the Park has been singularly fortunate. The names are in all cases characteristic. They are not studied efforts, but are simply the spontaneous utterances from first impressions by those who had never seen, and had heard but little of, similar phenomena. It is doubtful if the most careful study could improve them, and tourists will agree with General Poe who referred as follows to this subject when he visited the Park in 1877:[BZ] "The region of these geysers has been rightly named Fire Hole, and one almost wonders that in this country, where the tendency is to name natural objects after men who have a temporary prominence, this interesting place and its assemblage of wonders should have so completely escaped, and in general and in particular received names so very appropriate." [BZ] Page 79, "Inspection made in the Summer of 1877, etc." See Appendix E. In the race for the geographical honors of the Park, the prize fell neither to the United States Geological Survey nor even to Colonel Norris, though each was a close competitor. It was won by that mythical potentate of whose sulphurous empire this region is thought by some to be simply an outlying province. Starting with "Colter's Hell," the list grew until it contained "Hell Roaring Creek," "Hell Broth Springs," "Hell's Half Acre," "Satan's Arbor," and the Devil's "Den," "Workshop," "Kitchen," "Stairway," "Slide," "Caldron," "Punch Bowl," "Frying Pan," "Well," "Elbow," "Thumb," "Inkstand," etc., etc. It is some satisfaction to know that this rude and fiery nomenclature is gradually falling into disuse. In a measure from sympathy with the purpose of the early name-givers, and to help those who take an interest in such matters to know when, by whom, and why the geographical names of the Park were given, a complete list of these names, with a few from adjacent territory, has been prepared. The letters and numbers immediately after the names (except those in parentheses) give marginal references on the map to facilitate identification. The date of christening and the name of the christening party next follow. When these can not now be determined with precision, the work is credited to the authors of the map upon which they first appear. Next comes whatever account is discoverable of the origin of the names, authority being quoted, as far as possible, from the writings of whoever bestowed them. Wherever an object was named from some natural characteristic, as its form, color, composition, or other peculiarity, or from the birds, beasts, fishes, insects, trees, flowers, shrubs or minerals of the Park, the single word "characteristic" denotes the fact. The abbreviation "U. S. G. S." is for "United States Geological Survey." APPENDIX A. II. MOUNTAIN RANGES, PEAKS, BUTTES, RIDGES, HILLS.
