His lifetime measures that period of our history during which the West was changed from a trackless wilderness to a settled and civilized country. He was among the first who went to the mountains, and he lived to see all that had made a life like his possible swept away forever. His name survives in many a feature of our western geography, but in none with greater honor than in this little lake among the mountains that he knew so well; and near the source of that majestic stream with which so much of his eventful life was identified. _Delusion Lake_ (7,850)--M: 9--1878--U. S. G. S.--This lake was long supposed to be an arm of the Yellowstone Lake, and, in the fanciful comparison of the main lake to the form of the human hand, occupied the position of the index finger. The delusion consisted in this mistaken notion of a permanent connection between the two lakes. _Dryad Lake_ (8,250)--K: 8--1885--U. S. G. S.--Characteristic. _Duck Lake_ (7,850)--M: 7--1885--U. S. G. S.--Characteristic. _Fern Lake_ (8,150)--H: 11--1885--U. S. G. S.--Characteristic. _Frost Lake_--(7,350)--I: 14--Unknown-Characteristic. _Gallatin Lake_ (9,000)--E: 4--1885--U. S. G. S.--Source of the Gallatin River. _Goose Lake_ (7,100)--K: 4--1885--U. S. G. S.--Characteristic. _Grassy Lake_ (7,150)--R: 5--1885--U. S. G. S.--Characteristic. _Grebe Lake_ (7,950)--G: 8--1885--U. S. G. S.--Characteristic. _Grizzly Lake_ (7,490)--F: 5--1885--U. S. G. S.--Characteristic. _Hart Lake_ (7,469)--P: 9--According to Hayden, "long known to the hunters of the region as Heart Lake." Named prior to 1870 for an old hunter by the name of Hart Hunney who in early times plied his trade in this vicinity. He was possibly one of Bonneville's men, for he seems to have known the General well and to have been familiar with his operations. He was killed by a war party of Crows in 1852. The spelling, _Heart_, dates from the expeditions of 1871. The notion that the name arose from the shape of the lake seems to have originated with Captain Barlow. It has generally been accepted although there is really no similarity between the form of the lake and that of a heart. Lewis Lake is the only heart-shaped lake in that locality. Everts named Hart Lake, Bessie Lake, after his daughter. _Henry Lake_ (6,443)--A noted lake outside the limits of the Park passed by tourists entering the park from the west. It is named for a celebrated fur trader, Andrew Henry, who built a trading post in that vicinity in 1809. _Hering Lake_ (7,530)--R: 5--1878--U. S. G. S.--For Rudolph Hering, Topographer on the Snake River Division of the Hayden Survey for 1872. _Indian Pond_--J: 11--1880--Norris.--An ancient, much-used camping-ground of Indians. "My favorite camp on the Yellowstone Lake (and it evidently has been a favorite one for the Indian) has ever been upon the grove-dotted bluff, elevated thirty or forty feet above the lake, directly fronting Indian Pond."--Norris.
