Roy Johnson kicks off our Evolution of Grand Canyon Science series, and with good reason - he started the whole research project in the first place. Roy sits down with Brian and Steve Carothers to chat about forming and conducting the first significant studies in the Grand Canyon after the completion of Glen Canyon Dam. Enjoy Roy Johnson!
