Not long after Keith became a Ranger for the GCNP our parents, Ken and Esther Green and the family visited. We accompanied him on an Interpretive walk on the South Rim. I watched in awe as he pointed out Canyon features on the opposite rim and below. I knew what his visitors did not, that he couldn't even see his feet much less what he was accuratly pointing toward. I was struck by how well he knew the Canyon and what a perfect role he filled for the Park Service in spite of their reluctance to hire him. Our Bro was a great one and terribly missed. RIP, Keith.
