The Rocky Mountains

New Orleans is one of the flattest cities in the United States-- so flat that some consider it a bowl because most of the city is lower than sea level. In 1933, the Works Progress Administration built "Monkey Hill" at the Audubon Zoo which at the time was the highest point in the city, measuring only 27.5 feet above the ground. In the year 2000, Monley Hill was remodeled to be decorated for the zoo and after 67 years, the hill had lowered by about 11 feet, making it only 16 feet high now. In comparison to the 14,439 feet of Mount Elbert in the Rocky Mountains, New Orleans is as flat as can be!
