_Kingman Pass_ (7,230)--D: 6--1883--U. S. G. S.--The pass of which Golden Gate is the northern entrance. For Lieutenant D. C. Kingman, Corps of Engineers, U. S. A., who built the road through the pass. _Norris Geyser Basin_ (7,527)--G-H: 6--For P. W. Norris, who first explored and described it, and opened it up to tourists. It was, however, discovered in 1872 by E. S. Topping and Dwight Woodruff, who were led in that direction by noticing from the summit of Bunsen Peak a vast column of steam ascending to the southward. The day after this discovery, a tourist party, including a Mr. and Mrs. H. H. Stone, of Bozeman, Montana, visited it from Mammoth Hot Springs, and then continued their course, by way of the general line of the present route, to the Firehole Geyser Basin. Mrs. Stone was the first white woman to visit the Park. _Norris Pass_ (8,260)--M : 6--1879--Norris--For its discoverer. _Raynolds Pass_ (6,911)--Not on map.--Crosses the Continental Divide to the northward of Henry Lake, and connects the valley of Henry Fork with that of the Madison. Named for Captain W. F. Raynolds, who led his expedition through it in 1860. _Sylvan Pass_ (8,650)--L : 13--1895--U. S. G. S.--Characteristic. _Targhee Pass_ (7,063)--Not on map.--Crosses the Continental Divide to the eastward of Henry Lake, and leads from the valley of Henry Fork to that of the Madison. The origin and orthography of this name are uncertain. In Hayden's Report for 1872, occur three spellings, Targhee, Tyghee, and Tahgee. The weight of evidence is in favor of the form here adopted. There was an impression among the Hayden Survey people, in 1872, that the name was given in honor of some distinguished Indian Chief; but that there was no definite information on the point is evident from the following statements, taken from Hayden's Report for 1872. On page 56, it is stated that _Tahgee_ Pass "was named years ago for the head chief of the Bannocks." On page 227, it is said that _Tyghee_ Pass "was named for an old Shoshone chief who was wont to use it." The real origin is thus left somewhat obscure, but it is probable that the notion that the pass was named for an Indian chief may have some foundation in fact. There was living among the Bannocks within the present memory of white men a chief whose name was pronounced _Ti-gee_. APPENDIX A. VII. LIST OF THE PROMINENT GEYSERS. The numbers in the third column are the highest recorded eruptions. The numbers in the fourth and fifth columns are not to be taken as indicating the correct duration or periodicity of eruptions. The prevalent notion that geysers exhibit uniform periodicity of action, is erroneous. There is only one geyser of importance in the Park that can be depended on, and that is Old Faithful. The figures for the other geysers are merely rough averages, true, perhaps, as the mean of a year's observations, but not at all to be relied upon in predicting particular eruptions.
