In 2013, Hannock received the Olana Partnership Frederic E. Church Award along with co-honoree Elizabeth Broun, the Margaret and Terry Stent Director of the Smithsonian American Art Museum. The awards ceremony was held at the New York Public Library on May 23, 2013 with the theme “The Extraordinary American Landscape." The painter’s friend, the musician and art collector Sting presented Hannock’s award to him and a video tribute, featuring comments from Hannock collectors, was also shown. A painting by the artist, Niagara Falls, was among the featured items offered at the Benefit Auction.
