This is actually a true story, but it happened in the summer of 1978 when Sears and Kellwood (an outdoor equipment manufacturer), was testing camping gear in the Yellowstone drainage of the High Uintas.
Hillary, age 59 then, was said to have had little trouble hiking Kings Peak and the Uintas.
No stranger to Utah, Hillary had also floated the Green River during 1969, as part of the centennial commemoration of John Wesley Powell's 1869 original exploration of the area. (Source: http://www.hupc.org)

And, Sir Hillary had first visited the High Uintas in July of 1962, when he and his family enjoyed a 4-day camping trip in the Granddaddy Basin area.
"New Zealand mountain climber and family thrilled with pack trip into High Uintas areas" was a July 19, 1962 headline in the Uinta Basin Standard newspaper.
Duchesne District Ranger Larry Colton served as a guide for the Hillarys, as the family hiked and fished.
According to the newspaper, Hillary's wife, Lady Louise, and their three children -- Peter, 7, Sarah, 5, and Belinda, 3. -- ventured into the primitive area of the High Uintas.
Sir Hillary was under contract with the U.S. Forest Service to make a report on campgrounds in the western U.S. that year.

The family began at Mirror Lake, backpacked into the Granddaddy Basin area and then returned to Mirror Lake. They did a lot of hiking, but not any serious peaks. Sir Hillary said this trip was for finding "smiling" and not "fierce" peaks, according to the newspaper account.
The only negative to the trip were all the mosquitoes that they encountered, but that they got used to them.
Another Utah newspaper, the Vernal Express, reported that on that 1962 trip, Sir Hillary declared it "absolutely wonderful."
