Summit of Denali

In 1903, Cook led an expedition to
Denali
Denali (), federally designated as Mount McKinley, is the highest mountain peak in North America, with a summit elevation of above sea level. It is the tallest mountain in the world from base to peak on land, measuring . On p. 20 of Helm ...
, during which he circumnavigated the range. He made a second journey in 1906, after which he claimed to have achieved the first summit of its peak with one other expedition crew member. Other members, including
Belmore Browne, whom Cook had left on the lower mountain, immediately but privately expressed doubt. Cook's claims were not publicly challenged until 1909 when the dispute with Peary over the North Pole claim erupted, with Peary's supporters claiming Cook's Denali ascent was also fraudulent.
Unlike
Harry Karstens and
Hudson Stuck in 1913, Cook had not taken photographs from atop Denali. His alleged photo of the summit was found to have been taken on
a small outcrop on a ridge beside the Ruth Glacier, away.
In late 1909, Ed Barrill, Cook's sole companion during the 1906 climb, signed an affidavit saying that they had not reached the summit. In the late 20th century, historians found that he had been paid by Peary supporters to deny Cook's claim. (Henderson writes that this fact was covered up at the time, but Bryce says that it was never a secret.) Up until a month before, Barrill had consistently asserted that he and Cook had reached the summit. His 1909 affidavit included a map correctly locating what came to be called
Fake Peak, featured in Cook's "summit" photo, and showing that he and Cook had turned back at the "Gateway" (north end of the Great Gorge, i.e. adjacent to
Mount Barrille), 12 horizontal bee-line miles from Denali and below its top.
Climber
Bradford Washburn gathered data, repeated the climbs, and took new photos to evaluate Cook's 1906 claim. Between 1956 and 1995, Washburn and Brian Okonek identified the locations of most of the photographs Cook took during his 1906 Denali foray and took new photos at the same spots. In 1997 Bryce identified the locations of the remaining photographs, including Cook's "summit" photograph; none were taken anywhere near the summit. Washburn showed that none of Cook's 1906 photos were taken past the Gateway.
A 1910 expedition by the Mazama Club reported that Cook's map departed abruptly from the landscape at a point when the summit was still distant. Critics of Cook's claims have compared Cook's map of his alleged 1906 route with the landscape of the last . Cook's descriptions of the summit ridge are variously claimed to bear no resemblance to the mountain and to have been verified by many subsequent climbers. In the 1970s, climber Hans Waale found a route that fitted both Cook's narrative and descriptions. Three decades later, in 2005 and 2006, this route was successfully climbed by a group of Russian mountaineers.
No evidence of Cook's purported journey between the "Gateway" and the summit has been found. His claim to have reached the summit is not supported by his photos' vistas, his two sketch maps' markers, and peak-numberings for points attained. Similarly, neither his recorded compass bearings, barometer readings, route-map, nor camp trash support his claim of reaching the summit. In contrast, evidence in all of these categories have been found short of the Gateway.

Cook and his two companions were gone from Annoatok for 14 months, and their whereabouts in that period is a matter of intense controversy. In the view of Canadian historian

(Berton, 2001), Cook's story of his trek around the Arctic islands is probably legitimate. Other writers have relied on later accounts told by Cook's companions to investigators, who seemed to present another view.
There are similarities between Ahpellah and Etukishook's sketched route of their journey south, and the route taken by the fictional shipwrecked explorers in

Robert Peary
Robert Edwin Peary Sr. (; May 6, 1856 – February 20, 1920) was an American explorer and officer in the United States Navy who made several expeditions to the Arctic in the late 19th and early 20th centuries. He was long credited as being ...

Cook never produced detailed original navigational records to substantiate his claim to have reached the North Pole. He said that his detailed records were part of his belongings, contained in three boxes, which he left at Annoatok in April 1909. He had left them with

Cook intermittently claimed he had kept copies of his sextant navigational data, and in 1911 published some. These have an incorrect solar diameter. Ahwelah and Etukishook, Cook's Inuit companions, gave seemingly conflicting details about where they had gone with him. The major conflicts have been resolved in the light of improved geographical knowledge. Whitney was convinced that they had reached the North Pole with Cook, but was reluctant to be drawn into the controversy.
The Peary expedition's people (primarily
Matthew Henson, who had a working knowledge of Inuit, and George Borup, who did not) claimed that Ahwelah and Etukishook told them they had traveled only a few days from land. A map allegedly was drawn by Ahwelaw and Etukishook that correctly located and accurately depicted then-unknown

expedition so there could be no doubt concerning attainment of the pole if successful. Amundsen also had the advantage of traveling over a continent. He left unmistakable evidence of his presence at the South Pole, whereas any ice on which Cook might or might not have camped would have drifted many miles in the year between the competing claims.
At the end of his 1911 memoir, Cook wrote: "I have stated my case, presented my proofs. As to the relative merits of my claim, and Mr. Peary's, place the two records side by side. Compare them. I shall be satisfied with your decision."
Reputation
Cook's reputation never recovered from the attacks on his claim. While Peary's North Pole claim was widely accepted for most of the 20th century, it has since been discredited by a variety of reviewers, including the

. In April 1923, Cook and 24 other Fort Worth oil promoters were indicted in a federal crackdown on fraudulent oil company promotions. Three of Cook's employees pleaded guilty, but Cook insisted on his innocence and went to trial. Also tried was his head advertising copywriter, S. E. J. Cox, who had been previously convicted of mail fraud in connection with his own oil company promotions.
Among other deceptive practices, Cook was charged with paying dividends from stock sales, rather than from profits. Cook's attorney was former politician
Joseph Weldon Bailey, who clashed frequently with the judge. The jury found Cook guilty on 14 counts of fraud. In November 1923, Judge Killits sentenced Cook and 13 other oil company promoters to prison terms. Cook drew the longest sentence, 14 years 9 months. His attorney appealed the verdict, but the conviction was upheld.

Cook was imprisoned until 1930.
