Grand Canyon (Ariz.) -- Pictorial works

This collection includes portfolios of photographs and panoramic photographs created by Halverson that document the American West, 1987-2017.

The collection consists of photograph albums, lantern slides, and photographic negatives documenting Oastler's interest in wildlife and conservation, from 1909-1938. The 68 photograph albums document the Oastlers' trips to the West and elsewhere. Approximately 6400 lantern slides, most of them hand-colored, were used for Dr. Oastler's lectures on the West, and include nine panoramic lantern slides.
