Moore Field
Alton, Hidalgo County, Texas
Marker Inscription
A United States aviation training field, originally financed by the nearby cities of Edinburg, McAllen and Mission, was started here in 1941. Named for Lt. Frank M. Moore, a pilot killed in World War I, it was used for the training of World War II airmen. After the field was closed in 1945, the facilities were shared by a tri-cities commercial airport and the Weaver H. Baker Memorial Tuberculosis Hospital. Reactivated as Moore Air Force Base during the Korean War of the 1950s, the site has housed research offices of the United States Department of Agriculture since 1960. (1981)

The Story
Financed by the neighboring cities of Edinburg, McAllen, and Mission, Moore Field opened in 1941 as a U.S. aviation training base, named for Lt. Frank M. Moore, a pilot killed in World War I. It trained airmen throughout World War II before closing in 1945, was reactivated during the Korean War, and since 1960 has housed research offices of the U.S. Department of Agriculture. Its runways trace the long shadow of three American conflicts across a single Rio Grande Valley site.
Why it matters
Training fields like Moore turned rural America into the classroom of the air war, producing the thousands of pilots on whom mid-century American power depended.
The story behind this marker
AI contextThe era
In 1941 the United States was racing to prepare for a war it had not yet formally entered. American military aviation was small, and leaders knew that a modern air war would demand pilots in enormous numbers. A crash program was underway to build training fields wherever the conditions were right.
South Texas was ideal. The Lower Rio Grande Valley offered flat land, open skies and mild winters that allowed flying almost year-round. Across the South and Southwest, farm country was being transformed into airfields almost overnight, with runways, hangars and barracks rising where crops had grown.
The Valley's cities saw both patriotic duty and opportunity in hosting a field. A military base meant jobs, construction money and national attention for a region that was largely agricultural, and local communities competed to attract one.
People & events
Moore Field began as a local investment. The neighboring cities of Edinburg, McAllen and Mission helped finance the project, and construction started in 1941. That kind of civic partnership was common as towns pooled their resources to win a share of the military buildup.
The field took its name from Lt. Frank M. Moore, a pilot killed in World War I. Naming training bases after fallen aviators was a way of tying a new generation of fliers to those who had gone before. Young men who arrived to learn to fly carried the name of a man who had died in the first air war, in the infancy of military aviation.
Through the war years the field trained airmen for the fight. It closed in 1945, but its story did not end there. Its buildings were put to work for a tri-cities commercial airport and for the Weaver H. Baker Memorial Tuberculosis Hospital, a striking change from training warplanes to caring for patients. When the Korean War brought a new need for military readiness in the 1950s, the site was reactivated as Moore Air Force Base. Since 1960 it has housed research offices of the U.S. Department of Agriculture.
Its place in the American story
World War II was won in part by a training effort of staggering scale. The United States turned out pilots by the tens of thousands, and much of that work happened at fields like Moore, in places most Americans had never heard of. Rural and small-town America became the classroom of the air war.
Moore Field's later life is just as telling. Its conversion to an airport and a hospital mirrors what happened at former military sites across the country after 1945. Communities found new uses for wartime infrastructure, and medical uses like tuberculosis care reflected the public health challenges of the era.
The field's reactivation for the Korean War, and its later turn to agricultural research, trace the arc of the mid-century United States. One patch of Rio Grande Valley land served national defense, public health and the farm economy in turn, each answering the needs of its moment.
If you visit
Standing here, try to picture the roar of training aircraft over the flat Valley farmland, with young airmen from all over the country learning to fly under these wide South Texas skies.
The site today serves a very different purpose than it did in wartime. Look at the open, level terrain that made this such good flying country, and imagine the base built from scratch in a matter of months.
Moore Field pairs well with a broader tour of the Rio Grande Valley, a region rich in history from Spanish colonial days through the twentieth century. The nearby cities that financed the field, Edinburg, McAllen and Mission, each have their own historic sites worth exploring. Remember that this is an active research facility, so respect any signage about access.

Floyd H. (Slats) Rodgers
McAllen, TX
Floyd "Slats" Rodgers turned a boyhood love of kites into a barnstorming life in the sky, building his first airplane—"Old Soggy No. 1"—in 1912 and later flying war-surplus craft in a career that mixed stunt flying, crop dusting, and outright smuggling. A born rule-breaker, he was fined so often for illegal stunts that authorities long refused him a pilot's license. His crop-dusting work drew him to the Rio Grande Valley in the 1930s, where he settled and eventually died in McAllen.
Cpl. Harlon Block, USMC
Weslaco, TX
In February 1945, U.S. Marines fought to seize the small but strategic Pacific island of Iwo Jima, and Weslaco's own Corporal Harlon Block was among the six men who raised the American flag atop Mount Suribachi—an act frozen into one of the most famous photographs of World War II. Days later, after his squad leader was killed, Block took command but was himself killed within hours. His remains came home to Weslaco in 1949 and were later moved to the Iwo Jima monument in Harlingen.
Hilltop Gardens
Monte Alto, TX
Founded in 1939 by Lee and Sherman Ewald on a hilltop north of La Villa, Hilltop Gardens became one of the first commercial aloe vera farms in the United States, pioneering the crop's cultivation in the Rio Grande Valley. Lee Ewald developed aloe-gel cosmetics with her daughters, marketing them through a company incorporated in 1962 in what is believed to be a first use of aloe gel as a cosmetic ingredient. Under later owners the farm grew to hundreds of thousands of plants and became part of a major aloe-producing corporation, opening to the public in 2012 with the largest U.S. collection of aloe species.
Citrus Fruit Developed in Rio Grande Valley - Red-Meat Grapefruit
Weslaco, TX
The Rio Grande Valley's red-meat grapefruit was born of the region's saline-alkaline soil, bred from Thompson Pink budded onto sour orange rootstock. In 1929 nurserymen A. E. Henninger of Mission and Dr. J. R. Webb of Donna each found red fruit in their orchards; they cast lots, and Henninger won the right to patent his "Ruby Red" as U.S. Plant Patent No. 53, while Webb's "Red Blush" proved equally popular. Both rose-fleshed, red-tinged varieties became sweet, early-ripening favorites.
