The Rich Heritage of the TechRidge Mesa

History has prepared the TechRidge mesa for what it has and will become, from its rock-solid formation millennia ago, to the pioneering spirit that enabled modern use. As TechRidge, this treasured site will continue to serve St. George as a center of innovation for generations to come.

TechRidge History

The mesa’s natural inverted topography made it ideal for an airport, and the St. George Municipal Airport was dedicated here in 1940. At the time, building an airport at this location was a bold move, but one that served St. George well for many years.

First airmail arrives in St. George;
outgoing airmail is delivered to the airport on horseback


Municipal airport is dedicated, runway is blacktopped, small terminal constructed


First passenger flights between St. George and Salt Lake City


Modern Regional airport terminal is built


Airport terminal is enlarged


Municipal airport is closed; new regional airport opened at current location



The former airport property once known as the “Ridgetop Complex” was pegged for redevelopment as homes, schools, and retail. But with that airport now closed, city leaders began to reinvision their plans for this striking mesa into a walkable community of high-tech businesses, shops, restaurants, and living space called TechRidge.

Geological Formation

Mesas are some of the most show-stopping natural features of the St. George area. Rising from the middle of our city, the TechRidge mesa is one of the most stunning.

It was formed between 2.3 million to 20,000 years ago, as lava from small volcanoes flowed into lower-lying valleys. The lava flows cooled and hardened into black lava rock called basalt, which now tops the mesa.

Because basalt is less prone to erosion than sandstone and shale, thousands of years of erosion lowered the surrounding red rock to become the new valley floor. This left the basalt-crested mesas standing higher than their surroundings.
