Mapping the Grand Canyon article
“By 1974, the fieldwork had entailed around a dozen trips by the Washburns that amounted to 147 days in the canyon, almost 700 helicopter landings, thousands of measured distances and angles, and around 100 miles of triple-checked trail measurements. The costs, split between National Geographic and the Museum of Science, had topped $100,000, equivalent to nearly half a million dollars today. But the hardest part was yet to come.”

I have a copy of the map somewhere here in a storage box. Extraordinary map by a man who led an extraextraordinary life.
A list of his accomplishments is mind boggling considering how long that he was active.
I have his map of Denali too somewhere here along with signed editions of some of his books.
