Also featured are an interpreted walk through the Garden of Eden with a literal depiction of the six days in the Genesis, a dark room with pictures of the planets and stars, scale models of Noah's Ark and the Tower of Babel, an Ice Age room, the Canyon Wall, describing how the Grand Canyon was formed in a matter of weeks or months, rather than the millions of years posited by most geologists, and the Hall of Scholars with pictures and biographies of scientists who believed in creationism rather than accepting evolution. It also has a display about the ICR's RATE project, an effort, in conjunction with other young Earth creationist organizations, to find evidence of a young earth.

Edgemoor Farm Dairy Farm was built as part of a dairy farm in 1913 in Santee, California. Edgemoor was part of a Spanish land grant to Maria Antonio Estudillo who married Miguel de Pedrorena, a native of Madrid. By the 1850s, through a variety of ways, individuals obtained portions of the grant and began to farm. Walter Hamlin Dupee purchased Edgemoor Farm in 1913 and built it into a national award-winning dairy farm, polo pony ranch and early tourist attraction. Such was his prominence that the Guernsey Breeders Association in 1921 called his place "the foremost authority and breeder in the U.S.", having given the most grand champions at this ranch founded by John and Walter Dupee. Dupee said, "I am interested in pure breeding stock, modern equipment, and scientific methods, which I place at the disposal of all dairymen". A series of personal setbacks and problems brought Dupee to sell Edgemoor to Godfrey L. Strobeck.
