Ebright Azimuth is the recognized highest benchmark-monument elevation in Delaware at 447.85 feet above sea level, near Concord High School and close to the Pennsylvania border. Rather than a true mountain, it is a modest hilltop identified by a geodetic survey monument, named for James and Grant Ebright, with “azimuth” referring to an angular surveying measurement. Survey work has suggested that nearby ground may be slightly higher than the benchmark, underscoring its status as the official high point. The site also has communications significance through a 1947 Western Union microwave relay tower later adapted for VHF and UHF radio use. Delaware’s high point is among the nation’s lowest, exceeded only by Florida’s in low elevation.
