In June of 1989, a team of eight men ─ formally called The 1989 Mt. McKinley Global Positioning Expedition ─ set out from a base camp to perform one of the most unusual survey projects the world has ever seen. Their mission was to verify, by the most sophisticated satellite positioning methods, the true summit elevation and position of the highest mountain peak on the North American continent, Denali. [Mt. McKinley was renamed with its original name, Denali, in 2015]. The project involved hundreds of hours of planning, thousands of dollars in costs, the use of the most up to date global positioning equipment to track several special military communication satellites orbiting the earth . . . and one Berntsen Survey Monument, which was placed precisely at the summit.
