Since 1968, the United States Department of the Interior, through the New York Society of Illustrators, has sponsored a program called "Artist in the Parks." Artists are chosen to travel to national parks to draw and paint the land. The National Park Service displays their work in touring exhibitions designed to acquaint Americans with the beauty of their national parks. Murray Tinkelman visited Colorado National Monument, Dinosaur National Monument, Black Canyon of the Gunnison National Monument, and Flaming Gorge National Monument as a participant in the program. He produced twenty-five landscapes, several of which now reside in the permanent collection of the Smithsonian Institute in Washington, DC.

"Murray Tinkelman perceived in the American landscape those magical qualities he finds in all things. His magnificent mountains are awesome, and endowed with the delight of a child seeing something wonderful. These drawings embody Tinkelman's robust enthusiasm for everything he sees. He conjures up, in black and white, the colors of the vast land, the shapes that take us by surprise, the excitement of seeing it for the first time."
