(C.E. 1881- C.E. 1940)
Archaeologist, Park Ranger, & NPS Regional Superintendent
He went on to become the superintendent of the Southwestern National Monuments. Pinkley administered 27 national monuments across Arizona, New Mexico, Colorado and Utah. He was excitedly planning the development of Organ Pipe Cactus National Monument at the time of his death in 1940. "The Boss," as Pinkley was affectionately known, left an extraordinary legacy. Pinkley wrote monthly essays and articles to his staff, which were compiled into the collection, Ruminations from the Boss. The interesting, often humorous essays written by Pinkley revealed his uncanny ability to explain, instruct, and entice his fellow Park Rangers in a fatherly way.
