"The Patrotic Rock is located 12 miles north of Greenfield, Iowa, and one mile south of Interstate 80 on Highway 25 at the entrance of the Jefferson Rock Quarry. Each year before Memorial Day, Ray “Bubba” Sorensen paints the 12-foot-tall rock out of respect to veterans."
"Every year, for the last five years, a talented artist, Ray has done a Memorial Day tribute to our servicemen and servicewomen, both past and present, with a stirring tableau painted on a large granite boulder which stands next to Highway 25. The huge granite boulder came out of the nearby Schillberg Rock Quarry and it weighs approx. 56 ton (50.8Mg) and is 12 ft (3.7m) high."
"Sorensen paints over the previous years mural with white paint and starts with a blank canvas. He draws a sketch of his idea on paper and then draws the design by free hand onto the rock. This takes him anywhere from one to three weeks to paint. He gets his ideas from books, movies, previous artwork and images by other artists."
