Castolon
Open-knowledge reference entry
Castolon, also known as La Harmonia Ranch and Campo Santa Helena, is a tourist ghost town in southwestern Texas, United States, located in what is now Big Bend National Park along the Rio Grande. The location was first settled in 1901 by Cipriano Hernandez, who farmed the area and built the original Castolon Store, now known as the Alvino House.
History
The area began to attract refugees from nearby Mexico who were fleeing the Mexican Revolution of 1910. The Castolon area was the site on a U.S. Army encampment, called Campo Santa Helena, to house units patrolling the Mexican–American border. However, by the time the camp was complete in 1920 the border was quiet and the camp buildings were never used by the Army. In 1921 the La Harmonia Company was established in the barracks, operating a trading post and farming cotton. The La Harmonia Company was established in 1918 by Howard Perry, who owned the Chisos Mining Company in Terlingua, in partnership with Wayne Cartledge. Cartledge and his son Eugene chose the name and managed the company. The La Harmonia Company lasted until 1961, when it was sold to the National Park Service. The store was heavily damaged in a fire in May 2019.
This brief starts where responsible research should: with the source description of “Castolon” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q5050682. Authority coordinates are 29.133, -103.514. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1901, 1910, 1920 and 1921.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
