During October, 1968, January, May, July-August, and October 1969 field and laboratory work was carried out on parasites of elk in or near the Grand Teton National Park. Elk fecal analyses were made during each of the four seasons to learn more of the change in incidence of various internal parasites. Most of the research effort was directed toward field and laboratory work on the elk lungworm, Dictyocaulus sp. Project Number 156.
