De Lacy felt deeply wronged by this action, and Dr. Hayden promised him that he would set the matter right; but nothing was done. At a later day, Colonel Norris endeavored to do De Lacy tardy justice by placing his name on the stream which enters the lake from the north and drains the beautiful valley now crossed by the tourist route. This name remained for several year's, when it also was removed by the United States Geological Survey, and its place filled by "Heron Creek." During the past year, however, the name "De Lacy Creek" has been restored. _Summit Lake_ (8,450)--M: 3--1885--U. S. G.

This lake was named, on the map showing "Colter's Route in 1807," Lake Eustis, in honor of William Eustis, Secretary of War to President Madison, 1809 to 1812. Later it appears as Sublette Lake, in honor of the noted fur trader, William Sublette. It is even said at one time to have borne the "fugitive name," Riddle Lake. But it early became known by its present name. * * * * * The islands of this lake are seven in number. They seem to have all been named by the United States Geological Survey largely for the employes of the survey. They are: _Carrington Island._ For Campbell Carrington, zoologist. _Dot Island._ A mere dot on the map. _Frank Island._ For the brother of Henry W. Elliott, a member of the Hayden Expedition of 1871. This Island was renamed Belknap Island in 1875 by the members of Secretary Belknap's party, who passed through the Park in that year. The name, however, never came into use. _Molly Island._--For the wife of Mr. Henry Gannett. _Peale Island._--For Dr. A. C. Peale, author of the elaborate report on thermal springs which appears in Hayden's report for 1878. _Pelican Roost._--Characteristic. _Stevenson Island._--For James Stevenson. See "Mt. Stevenson." * * * * * The bays are also seven in number, of which only the following merit notice: _Mary Bay._--Named by Henry W. Elliott for Miss Mary Force. _Thumb._--From the old fancy that the form of the lake resembled that of the human hand. _Bridge Bay._--From Bridge Creek. See "Bridge Creek."
