In 1926, Tom T. Terrell joined Jim Evenden's staff at the Coeur d'Alene, Idaho, Forest Insect Lab and conducted the first aerial survey of Yellowstone N.P. in 1930. He is shown here in 1932 beside an open cockpit airplane like that used on his landmark survey that marked the first such use of an aircraft in the northern Rocky Mountains (Furniss & Renkin 2003, Figure 3).
