Webb Hill is a mountain located approximately 2.2 miles (3.5 km) south of St. George, Utah, in Washington County. The mountain houses numerous radio and television tower facilities that serve the local area. The mountain's geology is common with the surrounding region.
As with the surrounding area, soil and rock formations on Webb Hill are red in appearance due to the presence of iron oxide. Although portions of the older section of the city of Saint George (particularly the southern part near the Virgin River) lie on floodplain alluvium, much of the town is built directly upon Jurassic, Triassic, and Permian period sedimentary bedrock. This includes Webb Hill. At its highest point, the hill reaches 3,120 feet (951 m) in elevation. It is 1.3 miles (2 km) in length from east to west, and 0.5 miles (1 km) in length from north to south.
In order of FM frequency, Webb hill houses transmitters for the following radio stations. Given these stations are translators and lower power stations, their coverage of the region is limited. Full power stations in St. George transmit from a different mountain located 17 miles south of town. They broadcast from a mountain known as Seegmiller Mountain, located in Arizona.
