From July 23-August 13, Sigurd was canoeing 500 miles of the Churchill River in Saskatchewan with the Voyageurs. He would later recount the trip in his 1961 book The Lonely Land. To read Voyageur Denis Coolican's trip diary, complete with links to maps and photos, click here.

August 1970 (age 71)

Sigurd is involved in a minor (though not to him) dispute with Alfred A. Knopf over the proposed title for his next book. His editor at Knopf wants to call it Sig Olson Country. Sigurd writes to his agent, Marie Rodell, "I simply cannot go along with that and never will. I'd rather cancel the whole project than consent." He reached a compromise that didn't attach his name to the entire region. The book would come out in 1972 with the title Sigurd F. Olson's Wilderness Days.
