Throughout his tenure at UM, K. Ross Toole remained an outspoken advocate for environmental responsibility and political ethics. Though undergoing treatment for the lung cancer that ultimately killed him, he spent the first months of 1981 living in Helena, writing and ``keeping an eye on the Legislature.'' His 1981 writing project remained unfinished, though, and Toole died in a Missoula County / Missoula city hospital that August. He remains, however, the state's best-known academic historian, with an influence that continues to be felt today.
