Webb Hill, Mountain summit in St. George, Utah, United States

Webb Hill is a hill in St. George, Utah, reaching 3,140 feet (957 m) and measuring 1.3 miles (2 km) east to west and 0.5 miles (1 km) north to south. Its soil and rock appear red from iron oxide, and the hill is built on Jurassic, Triassic and Permian sedimentary bedrock.

The area around Webb Hill shows evidence of Native American settlement spanning several centuries based on archaeological findings. These remains indicate a sustained presence in the region over time.

Broadcasting from the hill began with translators and low-power stations whose reach is limited to the St. George area; full-power stations transmit instead from Seegmiller Mountain, 17 miles south in Arizona. Among the transmitters are KMYU (digital channel 9), a full-service station, and KUEW (digital channel 18), a satellite of Salt Lake City's KUED. Seventeen television stations broadcast here, most of them low power, and several analog translators went silent with the national digital transition.

Webb Hill rises about 133 metres above the surrounding terrain and is roughly 1.9 kilometres wide at its base, with the summit about 4.6 kilometres north of central St. George. The slopes are mostly open desert scrub, so there is little shade; the surrounding landscape is dry, with about 298 millimetres of rain a year.

The summit functions as a broadcasting hub with multiple television and radio transmitters serving the region. This infrastructure presence creates an interesting contrast between the natural landscape and modern communication technology.
