In June 2017, Ray "Bubba" Sorensen painted a rock in Woodbury County with images honoring veterans, local history, and public service. The west face features Sgt. Charles Floyd and the Floyd Monument in Sioux City, Iowa. Floyd, a native of Kentucky, was a United States explorer, a non-commissioned officer in the U.S. Army, and quartermaster in the Lewis and Clear Expedition, and his daily record has been used extensively by historians. He was the only member of the Corps of Discovery to die on the Lewis and Clark Expedition, on August 20, 1804. Floyd's Bluff in southern Sioux City, Iowa, named for him, was his original burial site and is now the location of a National Historic Landmark; the Floyd Monument stands above the east bank of the Missouri River just downstream from the mouth of the Floyd River, and the bluff is part of the Loess Hills formation. The north face features Col. Bud Day, a Sioux City native and the most decorated veteran in U.S. history, who served as a United States Air Force colonel and pilot during World War II, the Korean War, and the Vietnam War, including five years and seven months as a prisoner of war in North Vietnam. Day received the Medal of Honor and the Air Force Cross, and as of 2016 he was the only person to have received both; President Gerald Ford presented him with the Medal of Honor in 1976. The east face depicts the B-17 bomber that crashed three miles southwest of Anthon on May 26, 1944, killing all 10 men aboard on its last training run from the Sioux City Army Air Base; the 10 bald eagles around it represent the 10 airmen killed. The crew members were 1st Lt. Roger G. Jay, Flight Officer John B. Smith, Flight Officer Lyland R. Petersen, 2nd Lt. Hubert B. Godbee, Cpt. James A. Williams, Pvt. Fred T. Littlewold, Cpl. James O. Hawkins, Pfc. Ray E. Snider, Pvt. Joseph A. Calvello, and Pfc. Norman Lindjord. Rick Bohle of Kingsley, Iowa, and his boy found pieces of metal from the wreckage, ground them into dust, and Sorensen mixed this dust into the paint used for the bomber image. The south face shows a sheriff's badge, EMS staff with a snake, and a fireman's hat with the number 61, representing the 61st Freedom Rock Sorensen painted in Iowa, and honors those who risk their lives to protect and save others, especially during the Flight 232 disaster on July 19, 1989, as well as the countless volunteers who serve Woodbury County communities.
