When he lived in the mountains of Alaska, was Richard Proenneke in full autonomy?

Context:
Richard Louis Proenneke (/ˈprɛnəkiː/; May 4, 1916 – April 20, 2003) was an American self-educated naturalist, conservationist, writer, and wildlife photographer who, from the age of about 51, lived alone for nearly thirty years (1968–1998) in the mountains of Alaska in a log cabin that he constructed by hand near the shore of Twin Lakes. Proenneke hunted, fished, raised and gathered much of his own food, and also had supplies flown in occasionally. He documented his activities in journals and on film, and also recorded valuable meteorological and natural data. The journals and film were later used by others to write books and produce documentaries about his time in the wilderness.<|im_end|>
