Though unquestionably many men traversed the region after the discovery of gold in Cook's Inlet in 1894, no other public recorded mention of the great mountain was made until W. A. Dickey, a Princeton graduate, journeyed extensively in the Sushitna and Chulitna valleys in 1896 and reached the foot of the glacier which drains one of the flanks of Denali, called later by Doctor Cook the Ruth Glacier. Dickey described the mountain in a letter to the New York _Sun_ in January, 1907, and guessed its height with remarkable accuracy at twenty thousand feet. Probably unaware that the mountain had any native name, Dickey gave it the name of the Republican candidate for President of the United States at that time--McKinley. Says Mr. Dickey: "We named our great peak Mount McKinley, after William McKinley, of Ohio, the news of whose nomination for the presidency was the first we received on our way out of that wonderful wilderness." In 1898 George Eldridge and Robert Muldrow, of the United States Geological Survey, traversed the region, and Muldrow estimated the height of the mountain by triangulation at twenty thousand three hundred feet. [Sidenote: Herron, Brooks, Wickersham] In 1899 Lieutenant Herron crossed the range from Cook's Inlet and reached the Kuskokwim. It was he who named the lesser mountain of the Denali group, always known by the natives as Denali's Wife, "Mount Foraker," after the senator from Ohio. In 1902 Alfred Brooks and D. L. Raeburn made a remarkable reconnoissance survey from the Pacific Ocean, passing through the range and along the whole western and northwestern faces of the group. They were the first white men to set foot upon the slopes of Denali. Shortly afterward, in response to the interest this journey aroused among Alpine clubs, Mr. Brooks published a pamphlet setting forth what he considered the most feasible plan for attempting the ascent of the mountain.
